继续循环迭代异常被抛出后， [英] Continue loop iteration after exception is thrown

问题描述

让我们说我有一个code是这样的：

Let's say I have a code like this:

try
{
    for (int i = 0; i < 10; i++)
    {
        if (i == 2 || i == 4)
        {
            throw new Exception("Test " + i);
        }
    }
}
catch (Exception ex)
{
    errorLog.AppendLine(ex.Message);
}

现在，很明显，该执行将停止我== 2 ，但我希望把它完成整个迭代，以使错误日志有两个条目（我== 2 和我== 4 ） 那么，是不是可以继续循环，甚至抛出异常？

Now, it's obvious that the execution will stop on i==2, but I want to make it finish the whole iteration so that in the errorLog has two entries (for i==2 and i==4) So, is it possible to continue the iteration even the exception is thrown ?

推荐答案

只要改变抓的范围是内循环，而不是在它之外：

Just change the scope of the catch to be inside the loop, not outside it:

for (int i = 0; i < 10; i++)
{
    try
    {
        if (i == 2 || i == 4)
        {
            throw new Exception("Test " + i);
        }
    }
    catch (Exception ex)
    {
        errorLog.AppendLine(ex.Message);
    }
}
