示例
下面的代码示例输出窗体上的每个 Binding 的 PropertyName 和 IsBinding 值。
Private Sub PrintBindingIsBinding
Dim c As Control
Dim b As Binding
For Each c In Me.Controls
For Each b in c.DataBindings
Console.WriteLine (ControlChars.CrLf & c.ToString)
Console.WriteLine (b.PropertyName & " IsBinding: " & _
b.IsBinding)
Next
Next
End Sub
private void PrintBindingIsBinding()
{
foreach(Control c in this.Controls)
{
foreach(Binding b in c.DataBindings)
{
Console.WriteLine("\n" + c.ToString());
Console.WriteLine(b.PropertyName + " IsBinding: "
+ b.IsBinding);
}
}
}
private:
void PrintBindingIsBinding()
{
for each ( Control^ c in this->Controls )
{
for each ( Binding^ b in c->DataBindings )
{
Console::WriteLine( "\n {0}", c );
Console::WriteLine( "{0} IsBinding: {1}",
b->PropertyName, b->IsBinding );
}
}
}
private void PrintBindingIsBinding()
{
for (int iCtr1 = 0; iCtr1 < this.get_Controls().get_Count(); iCtr1++) {
Control c = this.get_Controls().get_Item(iCtr1);
for (int iCtr2 = 0; iCtr2 < c.get_DataBindings().get_Count();
iCtr2++) {
Binding b = c.get_DataBindings().get_Item(iCtr2);
Console.WriteLine(("\n" + c.ToString()));
Console.WriteLine((b.get_PropertyName() + " IsBinding: "
+ b.get_IsBinding()));
}
}
} //PrintBindingIsBinding
private function PrintBindingIsBinding()
{
for(var c : Control in this.Controls)
{
for(var b : Binding in c.DataBindings)
{
Console.WriteLine("\n" + c.ToString());
Console.WriteLine(b.PropertyName + " IsBinding: "
+ b.IsBinding);
}
}
