Return Value

The Label control that was added to the ControlCollection instance.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ControlCollection. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Exceptions

Exception	Condition
ArgumentNullException	The name argument is nulla null reference (Nothing in Visual Basic) or has zero length.
ControlNameAlreadyExistsException	A control with the same name is already in the ControlCollection instance.

Remarks

The AddLabel method enables you to add Label objects to the end of the ControlCollection. To remove a Label control that was previously added programmatically, use the Remove method.

Examples

The following code example adds a Label control to the top of the worksheet, and then changes the text to First Name. To use this example, run it from the Sheet1 class in a document-level project.

Private Sub ExcelAddLabel()

        Dim Label1 As Microsoft.Office.Tools.Excel. _
            Controls.Label = Me.Controls.AddLabel( _
            0, 0, 75, 17.25, "Label1")
        Label1.Text = "First Name" 

    End Sub

private void ExcelAddLabel()
{

    Microsoft.Office.Tools.Excel.Controls.Label
        label1 = this.Controls.AddLabel(
        0, 0, 75, 17.25, "label1");
    label1.Text = "First Name";
}
