how to add a summary in c# code example

Example 1: c# summary tag

// compile with: -doc:DocFileName.xml 

/// text for class TestClass
public class TestClass
{
    /// <summary>DoWork is a method in the TestClass class.
    /// <para>Here's how you could make a second paragraph in a description. <see cref="System.Console.WriteLine(System.String)"/> for information about output statements.</para>
    /// <seealso cref="TestClass.Main"/>
    /// </summary>
    public static void DoWork(int Int1)
    {
    }

    /// text for Main
    static void Main()
    {
    }
}

Example 2: c# docstring

/// <summary>This method changes the point's location by
///    the given x- and y-offsets.
/// <example>For example:
/// <code>
///    Point p = new Point(3,5);
///    p.Translate(-1,3);
/// </code>
/// results in <c>p</c>'s having the value (2,8).
/// </example>
/// </summary>

public void Translate(int xor, int yor) {
    X += xor;
    Y += yor;
}
