我正在尝试在.NET Compact Framework 3.5上的表单应用程序中实现自定义消息框（确定，取消）。我该如何实现？

我和同事一起设计了以下类作为一种动态消息框。
这是设计者代码:
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.lblMessage = new System.Windows.Forms.Label();
this.btnRight = new System.Windows.Forms.Button();
this.btnLeft = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// lblMessage
//
this.lblMessage.AutoSize = true;
this.lblMessage.Location = new System.Drawing.Point(12, 39);
this.lblMessage.Name = "lblMessage";
this.lblMessage.Size = new System.Drawing.Size(35, 13);
this.lblMessage.TabIndex = 0;
this.lblMessage.Text = "label1";
//
// btnRight
//
this.btnRight.Anchor = System.Windows.Forms.AnchorStyles.Bottom;
this.btnRight.Location = new System.Drawing.Point(89, 73);
this.btnRight.Name = "btnRight";
this.btnRight.Size = new System.Drawing.Size(75, 23);
this.btnRight.TabIndex = 1;
this.btnRight.UseVisualStyleBackColor = true;
//
// btnLeft
//
this.btnLeft.Anchor = System.Windows.Forms.AnchorStyles.Bottom;
this.btnLeft.Location = new System.Drawing.Point(8, 73);
this.btnLeft.Name = "btnLeft";
this.btnLeft.Size = new System.Drawing.Size(75, 23);
this.btnLeft.TabIndex = 0;
this.btnLeft.UseVisualStyleBackColor = true;
//
// CustomMessageBox
//
this.AcceptButton = this.btnLeft;
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.AutoSize = true;
this.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
this.ClientSize = new System.Drawing.Size(170, 114);
this.ControlBox = false;
this.Controls.Add(this.btnLeft);
this.Controls.Add(this.btnRight);
this.Controls.Add(this.lblMessage);
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;
this.KeyPreview = true;
this.MinimumSize = new System.Drawing.Size(176, 120);
this.Name = "CustomMessageBox";
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterParent;
this.Text = "CustomMessageBox";
this.Load += new System.EventHandler(this.frmCustomMessageBoxLoad);
this.ResumeLayout(false);
this.PerformLayout();
}
#endregion
private System.Windows.Forms.Label lblMessage;
private System.Windows.Forms.Button btnRight;
private System.Windows.Forms.Button btnLeft;
这是表单背后的代码：
internal partial class CustomMessageBox : Form
{
#region Fields
public readonly MessageBoxButtons _buttons;
#endregion
//need to seal properties to override from derived class
#region Constructors
/// <summary>
/// This constructor is required for designer support.
/// </summary>
public CustomMessageBox()
{
InitializeComponent();
}
public CustomMessageBox(string message, string title, MessageBoxButtons buttons)
{
InitializeComponent();
Text = title;
lblMessage.Text = message;
_buttons = buttons;
}
#endregion
#region Properties
public override sealed string Text
{
get { return base.Text; }
set { base.Text = value; }
}
#endregion
#region private
private void frmCustomMessageBoxLoad(object sender, EventArgs e)
{
lblMessage.Left = (ClientSize.Width - lblMessage.Width) / 2;
switch(_buttons)
{
case MessageBoxButtons.OKCancel:
{
btnLeft.Text = @"OK";
btnLeft.DialogResult = DialogResult.OK;
btnRight.Text = @"Cancel";
btnRight.DialogResult = DialogResult.Cancel;
AcceptButton = btnLeft;
break;
}
case MessageBoxButtons.OK:
{
btnLeft.Text = @"OK";
btnLeft.DialogResult = DialogResult.OK;
btnRight.Hide();
btnLeft.Left = (ClientSize.Width - btnLeft.Width) / 2;
AcceptButton = btnLeft;
break;
}
case MessageBoxButtons.YesNo:
{
btnLeft.Text = @"Yes";
btnLeft.DialogResult = DialogResult.Yes;
btnRight.Text = @"No";
btnRight.DialogResult = DialogResult.No;
AcceptButton = btnLeft;
break;
}
default :
{
btnLeft.Hide();
btnRight.Hide();
break;
}
}
AcceptButton = btnLeft;
}
#endregion
}

需要解释。这个做了什么，标准的MessageBox选项没有做到的？最令人困惑的是，为什么你要费这么大劲，而代码似乎只支持标准的MessageBoxButtons - 我认为从标准消息框升级的第一步应该是更灵活地设置按钮上的文本。 - ToolmakerSteve
2这个表单的主要目的是为了控制模态对话框在屏幕上的位置。内置的对话框无法移动而不使用Windows钩子。另外，由于它是一个自定义表单，它可以像任何其他表单一样进行设计修改，这也是问题的主要重点。 - Logarr

如果你需要一个带有“确定”和“取消”按钮的消息框，你可以使用以下代码：
MessageBox.Show(this, "Message", "caption", MessageBoxButtons.OKCancel);
如果您想要自定义外观和感觉，并添加任何通常不在消息框中看到的按钮，则必须制作自己的表单来显示。

我倾向于同意@EhsanUllah的观点，因为第一部分只是一个链接，而第二部分显然是一条评论。 - Steve
Jonesy，仅包含链接的答案存在问题，如果链接失效，答案将变得无用。 - Sayse

MessageBox()的工作方式，那么你需要使用Form.ShowDialog()。如果你想让Form.ShowDialog()返回数据，你需要设置Form.DialogResult属性。 - j.i.h.
