Indexers Sample

This sample shows how C# classes can declare indexers to provide array-like access to the classes.

To get samples and instructions for installing them

  • Do one or more of the following:

    • On the Help menu, click Samples.

      The Readme displays information about samples.

    • Visit the Visual Studio 2008 Samples Web site. The most recent versions of samples are available there.

    • Locate samples on the computer on which Visual Studio is installed. By default, samples and a Readme file are installed in drive:\Program Files\Microsoft Visual Studio 9.0\Samples\lcid. For Express editions of Visual Studio, all samples are located online.

For more information, see Visual Studio Samples.

To build and run the Indexers sample within Visual Studio

  1. In Solution Explorer, right-click the indexers project, and then click Properties.

  2. Open the Configuration Properties folder, and click Debug.

  3. In the Command Line Arguments property, type ..\..\Test.txt.

  4. Click OK.

  5. On the Debug menu, click Start Without Debugging.

To build and run the Indexers sample from a command prompt

  1. To compile the sample program, type the following at a command prompt:

    csc indexer.cs
  2. The sample program reverses the bytes in a file given as a command-line argument. For example, to reverse the bytes in Test.txt and see the result, issue the following commands:

    indexers Test.txt
    type Test.txt
  3. To change the reversed order, run the program on the same file again.
