Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public static bool ContainsFileDropList ()

The Clipboard could not be cleared. This typically occurs when the Clipboard is being used by another process.

ThreadStateException

The current thread is not in single-threaded apartment (STA) mode. Add the STAThreadAttribute to your application's Main method.

A file drop list is a collection of strings containing path information for files.

Use this method to determine whether the Clipboard contains a file drop list before retrieving it with the GetFileDropList method.

NoteNote

The Clipboard class can only be used in threads set to single thread apartment (STA) mode. To use this class, ensure that your Main method is marked with the STAThreadAttribute attribute.

The following example demonstrates this member.

// Demonstrates SetFileDropList, ContainsFileDroList, and GetFileDropList
public System.Collections.Specialized.StringCollection
    SwapClipboardFileDropList(
    System.Collections.Specialized.StringCollection replacementList)
{
    System.Collections.Specialized.StringCollection returnList = null;
    if (Clipboard.ContainsFileDropList())
    {
        returnList = Clipboard.GetFileDropList();
        Clipboard.SetFileDropList(replacementList);
    }
    return returnList;
}
