public:
property System::Windows::Forms::DialogResult DialogResult { System::Windows::Forms::DialogResult get(); void set(System::Windows::Forms::DialogResult value); };
public System.Windows.Forms.DialogResult DialogResult { get; set; }
member this.DialogResult : System.Windows.Forms.DialogResult with get, set
Public Property DialogResult As DialogResult
属性值
DialogResult 值之一。
示例
下面的示例继承自 ButtonBase 类并实现 IButtonControl 接口。 将实现添加到 DialogResult 属性和 NotifyDefault 和 PerformClick 方法。
#using <System.dll>
#using <System.Drawing.dll>
#using <System.Windows.Forms.dll>
using namespace System;
using namespace System::Windows::Forms;
using namespace System::Drawing;
public ref class MyButton: public ButtonBase, public IButtonControl
{
private:
System::Windows::Forms::DialogResult myDialogResult;
public:
MyButton()
{
// Make the button White and a Popup style
// so it can be distinguished on the form.
this->FlatStyle = ::FlatStyle::Popup;
this->BackColor = Color::White;
}
property System::Windows::Forms::DialogResult DialogResult
{
// Add implementation to the IButtonControl.DialogResult property.
virtual System::Windows::Forms::DialogResult get()
{
return this->myDialogResult;
}
virtual void set( System::Windows::Forms::DialogResult value )
{
if ( Enum::IsDefined( System::Windows::Forms::DialogResult::typeid, value ) )
{
this->myDialogResult = value;
}
}
}
// Add implementation to the IButtonControl.NotifyDefault method.
virtual void NotifyDefault( bool value )
{
if ( this->IsDefault != value )
{
this->IsDefault = value;
}
}
// Add implementation to the IButtonControl.PerformClick method.
virtual void PerformClick()
{
if ( this->CanSelect )
{
this->OnClick( EventArgs::Empty );
}
}
};
using System;
using System.Windows.Forms;
using System.Drawing;
public class MyButton : ButtonBase, IButtonControl
{
private DialogResult myDialogResult;
public MyButton()
{
// Make the button White and a Popup style
// so it can be distinguished on the form.
this.FlatStyle = FlatStyle.Popup;
this.BackColor = Color.White;
}
// Add implementation to the IButtonControl.DialogResult property.
public DialogResult DialogResult
{
get
{
return this.myDialogResult;
}
set
{
if(Enum.IsDefined(typeof(DialogResult), value))
{
this.myDialogResult = value;
}
}
}
// Add implementation to the IButtonControl.NotifyDefault method.
public void NotifyDefault(bool value)
{
if(this.IsDefault != value)
{
this.IsDefault = value;
}
}
// Add implementation to the IButtonControl.PerformClick method.
public void PerformClick()
{
if(this.CanSelect)
{
this.OnClick(EventArgs.Empty);
}
}
}
Imports System.Windows.Forms
Imports System.Drawing
Public Class MyButton
Inherits ButtonBase
Implements IButtonControl
Private myDialogResult As DialogResult
Public Sub New()
' Make the button White and a Popup style ' so it can be distinguished on the form.
Me.FlatStyle = FlatStyle.Popup
Me.BackColor = Color.White
End Sub
' Add implementation to the IButtonControl.DialogResult property.
Public Property DialogResult() As DialogResult Implements IButtonControl.DialogResult
Get
Return Me.myDialogResult
End Get
Set
If [Enum].IsDefined(GetType(DialogResult), value) Then
Me.myDialogResult = value
End If
End Set
End Property
' Add implementation to the IButtonControl.NotifyDefault method.
Public Sub NotifyDefault(value As Boolean) Implements IButtonControl.NotifyDefault
If Me.IsDefault <> value Then
Me.IsDefault = value
End If
End Sub
' Add implementation to the IButtonControl.PerformClick method.
Public Sub PerformClick() Implements IButtonControl.PerformClick
If Me.CanSelect Then
Me.OnClick(EventArgs.Empty)
End If
End Sub
End Class
注解
当窗体使用 ShowDialog 方法显示为对话框,并且单击其中一个按钮时,按钮 DialogResult 的值将分配给窗体的 DialogResult 属性。
