C# 如何在WinForms中显示包含详细信息的消息框？
刚才我注意到，当属性设置为无效值时，VisualStudio会显示一个包含详细信息的消息框。例如： 是否可以在WinForms中创建这种类型的消息框 我尝试了以下代码：C# 如何在WinForms中显示包含详细信息的消息框？,c#,.net,winforms,messagebox,C#,.net,Winforms,Messagebox,刚才我注意到，当属性设置为无效值时，VisualStudio会显示一个包含详细信息的消息框。例如： 是否可以在WinForms中创建这种类型的消息框 我尝试了以下代码： MessageBox.Show("Error in Division Fill.\n" + ex.Message, "Information", MessageBoxButtons.OK,
MessageBox.Show("Error in Division Fill.\n" + ex.Message,
"Information",
MessageBoxButtons.OK,
MessageBoxIcon.Information,
MessageBoxOptions.RightAlign);
如何修复此错误并获得显示其他详细信息的消息框？您需要设置的以下属性以创建自定义对话框/消息窗口
MyDialog dialog=new MyDialog();
DialogResult result=dialog.ShowDialog();
if(result == DialogResult.OK)
{
//
}
有关Dialog read MSDN article的更多信息-只需编写您自己的对话框，就不会像您希望显示的方法那样出现重载。正如其他人所指出的，您应该编写一个具有所需功能的自定义对话框。有关这方面的帮助，您可以查看
PropertyGridSystem.Windows.Forms.PropertyGridInternal.GridErrorDlgSystem.Windows.Forms// Get reference to the dialog type.
var dialogTypeName = "System.Windows.Forms.PropertyGridInternal.GridErrorDlg";
var dialogType = typeof(Form).Assembly.GetType(dialogTypeName);
// Create dialog instance.
var dialog = (Form)Activator.CreateInstance(dialogType, new PropertyGrid());
// Populate relevant properties on the dialog instance.
dialog.Text = "Sample Title";
dialogType.GetProperty("Details").SetValue(dialog, "Sample Details", null);
dialogType.GetProperty("Message").SetValue(dialog, "Sample Message", null);
// Display dialog.
var result = dialog.ShowDialog();
您只需执行以下操作：
catch (Exception error)
{
throw new Exception("Error with details button! \n"+error);
}
我也遇到了同样的问题。我建议您使用windowsAPIcode包。 这个网站将是一个很大的帮助。只要正确地按照说明操作即可：基于（我投了赞成票）我写了以下内容。将它粘贴到您使用VS模板生成的表单中，它应该可以工作，可能只需进行一些调整 我的代码：
