On this article, we might be discussing the Streamwriter class within the C# programming language. The Streamwriter class is normally used for dealing with textual content knowledge in information; it helps in helping once we alter or add textual content in a file with its totally different strategies and constructors. The StreamWriter class is outlined within the System.IO namespace, and it’s an inheritance of the TextWriter class within the C# Programming Language.

Utilizing StreamWriter class in C# to put in writing textual content in a file in Ubuntu 20.04:

Now we are going to make the most of the Streamwriter class’s strategies and constructors to put in writing textual content in a “.txt” format file. The “C# file” might be compiled, and the textual content file might be edited utilizing the command line interface. We are going to open the desktop listing to create the C# file and the textual content file on our desktop for straightforward entry; for this; we are going to use the “ cd Desktop “ command. After that, we’ll create a “.cs” file wherein we’ll write a ” C# ” program to put in writing textual content to a textual content file.

Within the above code, we’ve got used the streamwriter class and made an object of the category to name its capabilities that may help us in writing textual content right into a file that we created on our desktop. The category object is then known as to get us entry to the “Write()” technique, which is accountable for writing textual content right into a textual content file, and the opposite technique, which is the “WriteLine()” technique which is accountable for writing a line right into a textual content file.

The terminal output will show that the info is saved efficiently. We may even open the “.txt” file that we made by discovering it on our desktop and double-checking the textual content.

As we are able to see beneath, the textual content file has some textual content written in it that we wrote in our code earlier, which additional confirms that our program executed the operation efficiently.

Inserting a line in a textual content file utilizing streamwriter class in C# in Ubuntu 20.04:

As we already wrote a phrase efficiently in a textual content file, we are going to transfer on to writing a complete in a textual content file. For this operation, we are going to use the “WriteLine()” operate, which permits us to put in writing textual content in traces in textual content information. We are going to write a C# program wherein we are going to create a file after which use the streamwriter class to put in writing a line in a textual content file.

We utilized the streamwriter class within the following code and generated an object of the category to make use of its process, the “WriteLine()” technique, which might allow us to write a line right into a file that we created on our desktop.

The information is saved efficiently because the command line terminal suggests. We’ll additionally validate the textual content within the “.txt” file we produced by discovering it on our desktop and viewing it.

The “.txt ” file reveals {that a} single line has been added to the textual content file, and this verifies that our program ran efficiently.

Inserting a number of traces in phrase in a textual content file utilizing streamwriter class in C# in Ubuntu 20.04:

Now our focus could be on including a number of traces to a textual content file utilizing the Streamwriter class in C#. We are going to initialize a textual content file on our desktop after which make an object of the Streamwriter class by which we are going to entry the operate of the Streamwriter class that’s “WriteLine()” for inserting textual content traces to the “.txt ” file.

Within the following code, we used the streamwriter class and constructed an occasion of the category to make use of its operations, which allowed us so as to add a number of traces to a file we made on our desktop. We used the “WriteLine()” technique of the StreamWriter class to put in writing a number of traces in our textual content file.

The terminal output will show successful message of the saving of the info in our textual content file. We may even confirm the saving of the info by opening and analyzing the textual content file that’s current on our desktop.

Because the file reveals that a number of traces have been up to date within the textual content file, which is a affirmation of including a number of traces of information in a textual content file. The usage of the “WriteLine()” is environment friendly for inserting and saving traces right into a textual content file, as our program suggests.

Saving a variable in a textual content file through the use of streamwriter class in C# programming language in Ubuntu 20.04:

On this instance, we are going to save a variable in a textual content file and carry out a mathematical operation earlier than saving it within the textual content file. We’ll begin by making a textual content file on our desktop after which initializing three integers and assigning two of them some worth, whereas the third integer would be the product of those two integers. After assigning values and capabilities, we are going to use the streamwriter class to save lots of the third integer variable within the textual content file.

Within the above code, we’ve got initialized 3 integer variables in our code and assigned two of them a price, whereas the third integer is said to be the product of the primary two integers. After that, we used the “Write()” technique to insert and save these variables into the textual content file.

The output message proven within the terminal supplies proof that the info in our textual content file is saved which will also be verified by viewing the textual content file from our desktop.

The textual content file reveals the road wherein the variable is saved. The resultant of the sum of the 2 integers, which is “8,” is displayed within the final a part of the road.

Utilizing StreamWriter class with FileStream class to create and insert knowledge right into a textual content file in C# programming language within the Ubuntu 20.04 setting:

For this instance, we might be utilizing the Streamwriter class with the FileStream class to create and save knowledge in a textual content file coherently. The filestream class is used for all capabilities associated to information within the C# programming languages like open, shut, learn and write. This class is outlined within the System.IO namespace in C# programming. The filestream class will create a file on our desktop through the use of its “Create” operate, whereas the StreamWriter class will avoid wasting knowledge in that file.

Within the above code, we’ve got used each the courses, that are FileStream and StreamWriter, to create a file on our desktop. By creating cases of the courses, we had been ready to make use of their “Create” and “Shut” capabilities.

The output of the terminal displays that the textual content file is created, and a few knowledge is saved in that file, which will also be accessed from the desktop for verification as proven beneath:

Conclusion:

On this article, we mentioned the StreamWriter class within the C# programming language. This class is normally known as upon once we are required so as to add textual content to a “ .txt ” file on the run time. The StreamWriter class has a number of capabilities that help in inserting and saving knowledge; these capabilities are accessed by cases. We carried out a number of examples of those cases and totally different eventualities within the Ubuntu 20.04 setting to have a greater understanding of the StreamWriter class.
