在程序调试/运行过程中，出于需要我们需要显示出一些信息，这时使用MessageBox.Show()是一个比较不错的选择。MessageBox类的静态方法Show有21个重载函数：

public static DialogResult Show(string text);
public static DialogResult Show(IWin32Window owner, string text);
public static DialogResult Show(string text, string caption);
public static DialogResult Show(IWin32Window owner, string text, string caption);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, bool displayHelpButton);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath, HelpNavigator navigator);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath, string keyword);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath, HelpNavigator navigator);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath, string keyword);
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath, HelpNavigator navigator, object param);
public static DialogResult Show(IWin32Window owner, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, string helpFilePath, HelpNavigator navigator, object param);

几个相关的枚举：

public enum MessageBoxButtons
{
    OK = 0,
    OKCancel = 1,
    AbortRetryIgnore = 2,
    YesNoCancel = 3,
    YesNo = 4,
    RetryCancel = 5,
}

    Error = 16,
    Hand = 16,
    Stop = 16,
    Question = 32,
    Exclamation = 48,
    Warning = 48,
    Information = 64,
    Asterisk = 64,
}

//标题为"木子屋",带"是/否"两个按钮
MessageBox.Show("URL:http://www.mzwu.com/", "木子屋",MessageBoxButtons.YesNo);
//标题为"木子屋",带"是/否/取消"三个按钮,显示一个信息类型的图标
MessageBox.Show("URL:http://www.mzwu.com/", "木子屋", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);
//标题为"木子屋",带"是/否/取消"三个按钮,显示一个警告类型的图标,默认选中第二个按钮
MessageBox.Show("URL:http://www.mzwu.com/", "木子屋", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning,MessageBoxDefaultButton.Button2);
