如何使用剃刀语法转换为对象

Question

@using System.Data
@model DataTable

@foreach (var row in Model.Rows)
{
   @row[]  // how do you cast this to a object?
}

如何使用Razor语法将@row转换为对象？

Answer 1

您可以编写常见的C＃代码：

@foreach (YourType row in Model.Rows)
{
     ...
}

或

@foreach (var row in Model.Rows)
{
    YourType casted = (YourType)row;
    ...
}

或者如果你不确定它是否可以施放：

@foreach (var row in Model.Rows)
{
    YourType casted = row as YourType;

    if (casted != null)
    {
        ...
    }
}

Answer 2

我今天遇到了这个问题。我使用的解决方案是使用括号：

@((YourType) row)
