How to Read and Write Text Files in C# Programming

What is StreamReader in C# programming?

How can you open a sequential access file using StreamReader in C# programming?

Explanation:

In C# programming, a StreamReader is a class that allows you to read text from a character stream. It is a convenient way to read data from a file in a sequential manner.

To open a sequential access file using StreamReader in C# programming, you can declare a StreamReader variable and use the File.OpenText method.

When working with text files in C# programming, the StreamReader class is commonly used for reading data from files. It provides methods for reading characters, lines, or entire files.

To open a sequential access file using StreamReader, you can use the File.OpenText method. This method creates a new StreamReader object and opens the specified file for reading. It automatically assigns the UTF8 encoding to the file.

Here is an example of how to use StreamReader to read text from a file:

StreamReader reader = File.OpenText(filename);

In the above code snippet, "reader" is the StreamReader object that will be used to read text from the file specified by the "filename" string.

By utilizing the StreamReader class and the File.OpenText method in C# programming, you can easily read text files and access the content within them for processing or manipulation.
