Beispiele

Im folgenden Beispiel wird diese Methode verwendet, um ein Array von Zeichenfolgen abzurufen, das alle in einem Datenobjekt verfügbaren Datenformate (systemeigenes und automatisches Konvertieren) angibt.

DataObject dataObject = new DataObject("Some string data to store...");

// Get an array of strings, each string denoting a data format
// that is available in the data object.  This overload of GetDataFormats
// returns all available data formats, native and auto-convertible.
string[] dataFormats = dataObject.GetFormats();

// Get the number of data formats present in the data object, including both
// auto-convertible and native data formats.
int numberOfDataFormats = dataFormats.Length;

// To enumerate the resulting array of data formats, and take some action when
// a particular data format is found, use a code structure similar to the following.
foreach (string dataFormat in dataFormats)
{
    if (dataFormat == DataFormats.Text)
    {
        // Take some action if/when data in the Text data format is found.
        break;
    }
    else if(dataFormat == DataFormats.StringFormat)
    {
        // Take some action if/when data in the string data format is found.
        break;
    }
}

Dim dataObject As New DataObject("Some string data to store...")

' Get an array of strings, each string denoting a data format
' that is available in the data object.  This overload of GetDataFormats

Dim dataFormats() As String = dataObject.GetFormats()

' Get the number of data formats present in the data object, including both

Dim numberOfDataFormats As Integer = dataFormats.Length

' To enumerate the resulting array of data formats, and take some action when

For Each dataFormat As String In dataFormats
    If dataFormat = System.Windows.DataFormats.Text Then
        ' Take some action if/when data in the Text data format is found.
        Exit For
    ElseIf dataFormat = System.Windows.DataFormats.StringFormat Then
        ' Take some action if/when data in the string data format is found.
        Exit For
    End If
Next dataFormat

Parameter

Gibt zurück

Ein Array von Zeichenfolgen, wobei jede Zeichenfolge den Namen eines Formats angibt, das von diesem Datenobjekt unterstützt wird.

Implementiert

Beispiele

Im folgenden Beispiel wird diese Methode verwendet, um ein Array von Zeichenfolgen abzurufen, das nur Datenformate angibt, die in einem Datenobjekt verfügbar sind (automatisch konvertierbare Datenformate werden gefiltert).

DataObject dataObject = new DataObject("Some string data to store...");

// Get an array of strings, each string denoting a data format
// that is available in the data object.  This overload of GetDataFormats
// accepts a Boolean parameter inidcating whether to include auto-convertible
// data formats, or only return native data formats.
string[] dataFormats = dataObject.GetFormats(false /* Include auto-convertible? */);

// Get the number of native data formats present in the data object.
int numberOfDataFormats = dataFormats.Length;

// To enumerate the resulting array of data formats, and take some action when
// a particular data format is found, use a code structure similar to the following.
foreach (string dataFormat in dataFormats)
{
    if (dataFormat == DataFormats.Text)
    {
        // Take some action if/when data in the Text data format is found.
        break;
    }
}
