如何生成C#文档到CHM或HTML文件？

如果没有,应该用什么来创建一个CHM或HTML文件？

代码示例：

/// <summary>
/// Convert a number to string
/// </summary>
/// <param name="number">An integer number to be converted to string</param>
/// <returns>Number as string</returns>
/// <example>
/// <code>
///     var s = MyMethod(5);
/// </code>
/// </example>
/// <exception cref="Exception">In case it can't convert</exception>
/// <remarks>
/// Whatever
/// </remarks>
public string MyMethod(int number)
{
    return number.ToString();
}
