C# 4.0 基于行和列Id替换Datatable中的单列值

我一直在MVC5应用程序中处理DataTable，有一个要求，我需要用新值替换DataTable中某行的特定列值，我已经用更新的值获得了行和列id号。但我需要一种用新值替换旧值的简单方法。 这就是我迄今为止所尝试的：

 public ActionResult Change(int RowId, int ColId, string NewValue, string OldValue)
 {            
    if (NewValue != OldValue) 
    {
            DataTable dataTable = new DataTable();
            //Here i will store value from session
            dataTable = Session["Table"] as DataTable;

            //Here i'll get entire Single Row record from the Data Table based on Row Id
            DataRow dataRow = dataTable.Rows[RowId];

            //Now i want to get column value by providing Column Id
            //DataColumn dataColumn = new DataColumn("ColId");
            //Here i'll store new value for that column
            dataColumn = NewValue;

            //Now Replace or Save new column value back to Datatable
            //dataTable.Columns.Remove("ColId");
            //dataTable.Columns.Add(dataColumn);
     } 
     return View();
}

有人能帮我保存/替换数据表中行和行中该特定列的新列值吗

我用以下代码解决了这个问题：

public ActionResult Change(int RowId, int ColId, string NewValue, string OldValue)
 {            
    if (NewValue != OldValue) 
    {
            DataTable dataTable = new DataTable();
            //Here i will store value from session
            dataTable = Session["Table"] as DataTable;

            //Here i'll get entire Single Row record from the Data Table based on Row Id
            DataRow dataRow = dataTable.Rows[RowId];

            //This is what i used to do replace value
         if (Convert.ToString(dataRow[ColId]) == OldValue)
         {
            dataRow[ColId] = NewValue;
            dataTable.AcceptChanges();
            Session["Table"] = dataTable;
         }
     } 
     return View();
}

实现这一点有多种方法

• table.Rows[RowId][ColId]=NewValue（可能需要写入table.acceptchanges（））

与我的相比，完美的单线解决方案。。。非常感谢。
