Clipboard.ContainsFileDropList Method

Definition

Indicates whether there is data on the Clipboard that is in the FileDrop format or can be converted to that format.

public:
 static bool ContainsFileDropList();
public static bool ContainsFileDropList ();
static member ContainsFileDropList : unit -> bool
Public Shared Function ContainsFileDropList () As Boolean

Returns

true if there is a file drop list on the Clipboard; otherwise, false.

Exceptions

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

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

Examples

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;
}
' Demonstrates SetFileDropList, ContainsFileDroList, and GetFileDropList
Public Function SwapClipboardFileDropList(ByVal replacementList _
    As System.Collections.Specialized.StringCollection) _
    As System.Collections.Specialized.StringCollection

    Dim returnList As System.Collections.Specialized.StringCollection _
        = Nothing

    If Clipboard.ContainsFileDropList() Then

        returnList = Clipboard.GetFileDropList()
        Clipboard.SetFileDropList(replacementList)
    End If

    Return returnList

End Function

Remarks

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.

Note

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.
