FormClosedEventArgs.CloseReason Property

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

FormClosedEventArgs.cs

Gets a value that indicates why the form was closed.

C#

public System.Windows.Forms.CloseReason CloseReason { get; }

Property Value

CloseReason

One of the CloseReason enumerated values.

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Form.FormClosed event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type Form named Form1. Then ensure that the event handler is associated with the Form.FormClosed event.

C#

private void Form1_FormClosed(Object sender, FormClosedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "CloseReason", e.CloseReason );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "FormClosed Event" );
}

Remarks

A Form can be closed because of a variety of reasons, both user-initiated and programmatic. The CloseReason property indicates the reason for the closure.
