C# DataGridview轉換為DataTable

如已綁定過數據源：

DataTable dt = (dataGridView1.DataSource as DataTable)

 

 

如未綁定過數據源：

　　　　 public DataTable GetDgvToTable(DataGridView dgv) { DataTable dt = new DataTable(); // 列強制轉換 for (int count = 0; count < dgv.Columns.Count; count++) { DataColumn dc = new DataColumn(dgv.Columns[count].Name.ToString()); dt.Columns.Add(dc); } // 循環行 for (int count = 0; count < dgv.Rows.Count; count++) { DataRow dr = dt.NewRow(); for (int countsub = 0; countsub < dgv.Columns.Count; countsub++) { dr[countsub] = Convert.ToString(dgv.Rows[count].Cells[countsub].Value); } dt.Rows.Add(dr); } return dt; }
