If we provide a relative path (just a name and extension) Visual Studio will place a file inside the projectName/bin/debug folder. StreamWriter writerAbsolutePath = new StreamWriter('C:\MyProject\test.txt') Īs we can see from the code above, we can provide the relative or absolute path to our file. StreamWriter writerRelativePath = new StreamWriter('test.txt') StreamReader readerAbsolutePath = new StreamReader('C:\MyProject\test.txt') StreamReader readerRelativePath = new StreamReader('test.txt') We can execute this initialization in a couple of ways but the most common is by only providing an address to the file: To create objects for the StreamReader and StreamWriter classes we need to use the standard initialization for the reference data types. Creating Objects for StreamWriter and StreamReaderĬreating Objects for StreamWriter and StreamReader.We are going to cover the following sections: Both of these classes exist in the System.IO namespace as well as many other classes for working with files and directories. The StreamReader and StreamWriter classes enable the reading and writing actions to a file. If you want to download the source code for our examples, you can do that from here StreamWriter and StreamReader C# Source Code.
