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 ();

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;
}

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.

Megjegyzés

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.
