c# - 根据列名获取数据

Question

如何使用Datarow根据列名检索数据？我正在尝试从我的第一次循环中循环数据库数据

//Trying to get data
DataRow dr = dsResult.Tables[1].Rows[0];
//trying to get data successful 

//what i trying to achieve is to retrieve data from database based on rows index and 
     column name
for(int i =0; i <datagridview.Rows.Count ; i++){

   string a = dr['ColumnName'].['RowsIndex'].toString(); //Failed

}

Answer 1

        for (int i = 0; i < dataTable.Rows.Count; i++)
        {
            DataRow dr = dataTable.Rows[i]; //Where the RowIndex
            string a = dr[0].ToString();    //Where the ColumnIndex or ColumnName
        }

Answer 2

尝试 ？

dr.Rows[RowsIndex]['ColumnName'].ToString()

Answer 3

您是否尝试过删除'columnName'规范之后的句点，并放置rows[i]["columnName"]而不是[columnName][rows]？
