我在VS2008，C＃中使用Addin，我需要显示消息（错误消息和其他）。
我不知道消息的长度，因此我想使用Scrollable MessageBox。
我从2007年开始发现这篇文章：Mike Gold 2007年7月30日
现在，2011年又有哪些好的组件？我想评估一些有关它的组件。
更新
另一个组件，但更旧：MessageBoxExLib http://www.codeproject.com/KB/dialog/MessageBoxEx.aspx
可自定义的.NET Winforms消息框。 http://www.codeproject.com/KB/dialog/Custom_MessageBox.aspx

拿一个：FlexibleMessageBox – A flexible replacement for the .NET MessageBox
这是一个经过测试的课程，可以无缝替换MessageBox.Show的所有用法，让您可以在一个类文件中获得更多功能，您可以轻松添加到项目中。

我刚刚实现了一个带有可滚动多行TextBox的简单表单，当我需要类似于显示长状态报告或应用程序捕获的异常时。如果您愿意，您可以更改边框等，使其看起来更像标签。然后只需要新的一个并调用它的ShowDialog方法，或者将它的实例化包装在一个类似于MessageBox的静态成员中。据我所知，.NET团队没有内置比MessageBox更灵活的东西。
评论编辑：
使用可以使用静态方法显示的文本框创建窗口的代码非常简单。虽然我一般不喜欢公开的代码请求，但这次我还是要求：
public class SimpleReportViewer : Form
{
/// <summary>
/// Initializes a new instance of the <see cref="SimpleReportViewer"/> class.
/// </summary>
//You can remove this constructor if you don't want to use the IDE forms designer to tweak its layout.
public SimpleReportViewer()
{
InitializeComponent();
if(!DesignMode) throw new InvalidOperationException("Default constructor is for designer use only. Use static methods instead.");
}
private SimpleReportViewer(string reportText)
{
InitializeComponent();
txtReportContents.Text = reportText;
}
private SimpleReportViewer(string reportText, string reportTitle)
{
InitializeComponent();
txtReportContents.Text = reportText;
Text = "Report Viewer: {0}".FormatWith(reportTitle);
}
/// <summary>
/// Shows a SimpleReportViewer with the specified text and title.
/// </summary>
/// <param name="reportText">The report text.</param>
/// <param name="reportTitle">The report title.</param>
public static void Show(string reportText, string reportTitle)
{
new SimpleReportViewer(reportText, reportTitle).Show();
}
/// <summary>
/// Shows a SimpleReportViewer with the specified text, title, and parent form.
/// </summary>
/// <param name="reportText">The report text.</param>
/// <param name="reportTitle">The report title.</param>
/// <param name="owner">The owner.</param>
public static void Show(string reportText, string reportTitle, Form owner)
{
new SimpleReportViewer(reportText, reportTitle).Show(owner);
}
/// <summary>
/// Shows a SimpleReportViewer with the specified text, title, and parent form as a modal dialog that prevents focus transfer.
/// </summary>
/// <param name="reportText">The report text.</param>
/// <param name="reportTitle">The report title.</param>
/// <param name="owner">The owner.</param>
public static void ShowDialog(string reportText, string reportTitle, Form owner)
{
new SimpleReportViewer(reportText, reportTitle).ShowDialog(owner);
}
/// <summary>
/// Shows a SimpleReportViewer with the specified text and the default window title.
/// </summary>
/// <param name="reportText">The report text.</param>
public static void Show(string reportText)
{
new SimpleReportViewer(reportText).Show();
}
/// <summary>
/// Shows a SimpleReportViewer with the specified text, the default window title, and the specified parent form.
/// </summary>
/// <param name="reportText">The report text.</param>
/// <param name="owner">The owner.</param>
public static void Show(string reportText, Form owner)
{
new SimpleReportViewer(reportText).Show(owner);
}
/// <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()
{
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(SimpleReportViewer));
this.txtReportContents = new System.Windows.Forms.TextBox();
this.SuspendLayout();
//
// txtReportContents
//
this.txtReportContents.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
| System.Windows.Forms.AnchorStyles.Left)
| System.Windows.Forms.AnchorStyles.Right)));
this.txtReportContents.Location = new System.Drawing.Point(13, 13);
this.txtReportContents.Multiline = true;
this.txtReportContents.Name = "txtReportContents";
this.txtReportContents.ReadOnly = true;
this.txtReportContents.ScrollBars = System.Windows.Forms.ScrollBars.Both;
this.txtReportContents.Size = new System.Drawing.Size(383, 227);
this.txtReportContents.TabIndex = 0;
//
// SimpleReportViewer
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(408, 252);
this.Controls.Add(this.txtReportContents);
this.Icon = Properties.Resources.some_icon;
this.Name = "SimpleReportViewer";
this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Show;
this.Text = "Report Viewer";
this.ResumeLayout(false);
this.PerformLayout();
}
#endregion
private TextBox txtReportContents;
}
用法：
var message = GetSomeRidiculouslyLongMessage();
//assumes it's called from inside another Form
SimpleReportViewer.ShowDialog(message, "My Message", this);
此特定实现还支持使用Show（）方法的重载显示为普通的非对话窗口。

我正在为WPF寻找一个可滚动的消息框 - 然后我找到了MaterialMessageBox，这是（我认为）用于WPF的FlexibleMessageBox的漂亮外观。您可以从GitHub下载它：https://github.com/denpalrius/Material-Message-Box或将其作为nuget包安装在Visual Studio（https://www.nuget.org/packages/MaterialMessageBox/）中。
我发现的唯一问题是你不能在主线程之外使用它，所以我的解决方案是调用主线程并从那里显示消息：
mainWindow.Dispatcher.Invoke(() => MaterialMessageBox.Show("message text"));
