Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The Read a text file section of this article describes how to use the StreamReader class to read a text file. The Write a text file example 1 and the Write a text file example 2 sections describe how to use the StreamWriter class to write text to a file.
The following code uses the StreamReader class to open, to read, and to close the text file. You can pass the path write a program to process text files a text file to the Write a program to process text files constructor to open the file automatically.
The ReadLine method reads each line of text, and increments the file pointer to the next line as it reads. When the ReadLine method reaches the end of the file, it returns a null reference. For more information, see StreamReader Class. On the File menu, point to Newand then select Project. Write a program to process text files Visual C Projects under Project Typesand then select Console Application under Templates.
On the Debug menu, select Start to compile and to run the application. Press ENTER to close the Console window. The Console window displays the contents of the Sample. txt file：. The following code uses the StreamWriter class to open, to write, and to close the text file. In a similar way to the StreamReader class, you can pass the path of a text file to the StreamWriter constructor to open the file automatically.
The WriteLine method writes a complete line of text to the text file. This code creates a file that is named Test. txt on drive C. Open Test. txt in a text editor such as Notepad. txt contains two lines of text:. Unlike the previous example, this code passes two additional parameters to the constructor.
The first parameter is the file path and the file name of the file. The second parameter, truespecifies that the file is opened in append mode. If you specify false for the second parameter, the contents of the file are overwritten each time you run the code.
The third parameter specifies Unicodeso that StreamWriter encodes the file in Unicode format. You can also specify the following encoding methods for the third parameter:.
It's useful when you want to write one character at a time. On the File menu, point to Newand then click Project. Click Visual C Projects under Project Typesand then click Console Application under Templates.
This code creates a file that is named Test1. Open Test1. txt contains a single line of text: For all file manipulations, it's good programming practice to wrap the code inside a try-catch-finally block to handle errors and exceptions. Specifically, you may want to release handles to the file in the final block so that the file isn't locked indefinitely.
