Linq查询中的异常处理 [英] Exception handling in Linq queries

问题描述

我使用...

tmpLst = (from e in App.lstAllChilds where e.Id == Id select e).ToList();

其中 lstAllChilds 是列表，其中包含一些损坏的数据也是如此。

where lstAllChilds is the list, which contains some corrupted data as well.

所以现在可以处理这个查询中的Try-Catch块。

请帮助。

So now i m tying to handle Try-Catch block inside this query.
Please help.

推荐答案

以下是简单的更改，可以简单地排除null或引起异常的项目。

Here is the simplest change you can make to simply exclude items which are null or are raising an exception.

tmpLst = App.lstAllChilds.Where(e =>
{
    try
    {
        return e != null && e.Id == Id;
    }
    catch
    {
        return false;
    }
}).ToList();

但在我看来，您可能应该调查并解决潜在的问题。这似乎不是一个需要例外的场景。

But in my opinion you probably should investigate and solve the underlying problem. This doesn't seem like a scenario where exceptions should be expected.
