DataFormats.UnicodeText 字段

指定标准 Windows Unicode 文本格式。此 static 字段是只读的。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Shared ReadOnly UnicodeText As String
用法
Dim value As String

value = DataFormats.UnicodeText

public static readonly string UnicodeText

public:
static initonly String^ UnicodeText

public static final String UnicodeText

public static final var UnicodeText : String

备注

IDataObject 接口和 DataObject 类使用此字段来指定数据类型。

当向 IDataObject 或 DataObject 的实现进行添加时，请将此字段用作 IDataObject.SetData 和 DataObject.SetData 方法的格式。

若要查看是否存在此类型的对象，请将此字段用作 IDataObject.GetDataPresent 和 DataObject.GetDataPresent 方法的格式。

若要获取此类型的对象，请将此字段用作 IDataObject.GetData 和 DataObject.GetData 方法的格式。
