.NET Framework 类库 |
克隆 DataTable 的结构,包括所有 DataTable 架构和约束。
[Visual Basic] Public Overridable Function Clone() As DataTable [C#] public virtual DataTable Clone(); [C++] public: virtual DataTable* Clone(); [JScript] public function Clone() : DataTable;
返回值
新的 DataTable,与当前的 DataTable 具有相同的架构。
备注
注意 如果这些类已经过派生,则副本也具有相同的派生类。
示例
[Visual Basic, C#, C++] 以下示例创建 DataTable 对象架构的复本。
[Visual Basic] Private Sub GetClone(ByVal myDataTable As DataTable) ' Get a clone of the original DataTable. Dim cloneTable As DataTable cloneTable = myDataTable.Clone() ' Insert code to work with clone of the DataTable. End Sub [C#] private void GetClone(DataTable myDataTable){ // Get a clone of the original DataTable. DataTable cloneTable; cloneTable = myDataTable.Clone(); // Insert code to work with clone of the DataTable. } [C++] private: void GetClone(DataTable* myDataTable){ // Get a clone of the original DataTable. DataTable* cloneTable; cloneTable = myDataTable->Clone(); // Insert code to work with clone of the DataTable. }
