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);
            }
        }
