c# WinForm 编程总结

1、清空DataGridView

 /// <summary>
         /// 清空DataGridView
         /// </summary>
         /// <param name="dg">DataGridView</param>
         public void ClearDataGridView(DataGridView dg)
         {
             try
             {
                 if (dg == null || dg.DataSource == null)
                 {
                     return;
                 }

                 DataTable dt = (DataTable)dg.DataSource;

                 dt.Rows.Clear();

                 dg.DataSource = dt;

             }
             catch (Exception e)
             {
                 string errorMsg = string.Format(@"清除{0} DataGridView数据时出错，错误原因：{1}", dg.Name, e.Message);

                 Platform.Log(LogLevel.Fatal, errorMsg);

                 AlifMessageBoxShowError(errorMsg);
             }
         }

2、清空C1FlexGrid

 /// <summary>
         /// 清空C1FlexGrid
         /// </summary>
         /// <param name="c1FG">C1FlexGrid</param>
         public void ClearC1FlexGrid(C1.Win.C1FlexGrid.C1FlexGrid c1FG)
         {
             try
             {
                 if (c1FG != null)
                 {
                     c1FG.Clear(C1.Win.C1FlexGrid.ClearFlags.Content);
                 }
             }
             catch (Exception e)
             {
                 string errorMsg = string.Format(@"清空{0} C1.Win.C1FlexGrid.C1FlexGrid数据时出错，错误原因：{1}", c1FG.Name, e.Message);

                 Platform.Log(LogLevel.Fatal, errorMsg);

                 AlifMessageBoxShowError(errorMsg);
             }
         }
