DataTable.DefaultView.Sort 不排序 [英] DataTable.DefaultView.Sort Doesn't Sort

问题描述

我对 DataTable.DefaultView.Sort 感到困惑.这是我想在其中使用的代码段.

I am confused on DataTable.DefaultView.Sort. Here is the segment of the code I want to use it in.

actionLogDT.DefaultView.Sort = "StartDate";

foreach (CustomerService.ActionLogStartEndRow logRow in actionLogDT)
{
  // code here
}

我看到的示例没有使用 foreach 循环，因此让我不知道如何处理它.它不像我认为的那样排序.

The samples I have seen don't use the foreach loop and thus is confusing me on how to process this. It isn't sorting as I thought it should be.

我看到 .DefaultView 返回一个视图，而 .Table 给出一个编译错误.

I see that .DefaultView returns a view, and .Table gives a compile error.

推荐答案

我不得不采取稍微不同的方法.这篇文章是我能找到的最接近我的代码的帖子.这是工作结果:

I had to take a slightly different approach. This post was the closest I could find to get my code to work. Here is the working result:

actionLogDT.DefaultView.Sort = "StartDate";
DataView dv = actionLogDT.DefaultView;

foreach (DataRowView logRow in dv) { . . . }

从那里我只需要将值转换回正确的类型.

From there I just have to cast the value back into it's proper type.

(string)logRow["Status"].ToString()
