Parameters

virtualPath: String

A String that represents the virtual path.

Returns

Examples

The following example uses the MapPath method to obtain the physical path of a subfolder. It then appends the file name that is read from the Text property of a TextBox control. The result is the absolute physical path to that file.

String fileNameString = this.MapPath(subFolder.Text);
fileNameString += "\\" + fileNameTextBox.Text;

Dim fileNameString As String  = Me.MapPath(subFolder.Text)
fileNameString += "\\" + fileNameTextBox.Text
