知识储备01：DataGridView列头字段转换为中文名称

如下图：

解决代码：

        //自动生成列表，列内容对齐方式，列宽度
        private void dataGridViewAutoField() {
            string strFields = ""; //查询SQL字段合集变量
            //拼接SQL查询字段
            for (int i = 0; i < dataGridView1.Columns.Count; i++)
            {
                strFields += "'" + dataGridView1.Columns[i].HeaderText + "',";
            }
            //去最后,
            strFields = strFields.Substring(0, strFields.Length - 1);

            //查询SQL中字段的中文名，类型，宽度
            string strSql = "";
            strSql = " SELECT fdname,chnname,fdtype,fdWidth FROM fldlist WHERE fdname IN (" + strFields.TrimEnd() + ") ";

            SqlConnection conn1 = new SqlConnection(string.Format(strSqlconnErp));
            conn1.Open();
            SqlDataAdapter da1 = new SqlDataAdapter(strSql, conn1);
            DataSet ds1 = new DataSet();
            da1.Fill(ds1, "table"); 

            //与dataGridView列表头进行匹配
            for (int i = 0; i < dataGridView1.Columns.Count; i++)
            {
                string szColumnName = dataGridView1.Columns[i].HeaderText; //列名 
                int intFdwidth = 0;
                //没找到时，保留原英文名
                if (ds1.Tables["table"].Rows.Count == 0)
                {
                    dataGridView1.Columns[i].HeaderText = szColumnName;
                }
                else
                {
                    for (int i2 = 0; i2 < ds1.Tables["table"].Rows.Count; i2++)
                    {
                        string strFdname = "";
                        string strChnname = "";
                        string strFdtype = "";
                        strFdname = ds1.Tables["table"].Rows[i2][0].ToString().TrimEnd();
                        strChnname = ds1.Tables["table"].Rows[i2][1].ToString().TrimEnd();
                        strFdtype = ds1.Tables["table"].Rows[i2][2].ToString().TrimEnd();
                        intFdwidth = Convert.ToInt32(ds1.Tables["table"].Rows[i2][3].ToString());
