如何从此方法获取列值？

Question

我有一个方法，用于从我的表中获取名为ItemNumber，ItemDescription，UnitDescription选定行的3列的值。我已经传递了该选定行的参数ItemId，并且必须获取不同变量中的每个列值。我不知道如何在它的工作。可谁能告诉我该怎么做this.Here是我的代码 -

public System.Collections.IEnumerable FetchDataItem(int id) 
    { 
     var row = (from t1 in context.InventoryUnit 
        join t2 in context.InventoryItem on t1.UnitId equals t2.UnitId 
        where t2.ItemId == id 
        orderby t2.ItemNumber, t2.ItemDescription 
        select new 
        { 

        t2.ItemNumber, 
        t2.ItemDescription, 
        t1.UnitDescription 
        }); 


     return row.ToList(); 
    }

Satpal给了一个很好的例子，但是如果你不想创建一个类你可以使用它并将其选为匿名类型。

public static void Main() 
{ 
    // Short example... 
    var rows = (from t1 in context.InventoryUnit 
       join t2 in context.InventoryItem on t1.UnitId equals t2.UnitId 
       where t2.ItemId == id 
       orderby t2.ItemNumber, t2.ItemDescription 
       select new 
       { 
        ItemNumber = t2.ItemNumber, 
        ItemDescription = t2.ItemDescription, 
        UnitDescription = t1.UnitDescription 
       }); 

    // Here you still have access to data and the types of the data. 

    foreach (var row in row) 
    { 
     // do something with the data.... 
     var someint = row.ItemNumber; 
     var someString = row.ItemDescription; 
     var someotherstring = row.ItemDescription; 
    } 
}
