c# - 重启正在运行的函数

Question

我有一个函数可以调用每个对象的测试。如果当前测试失败，我希望能够重新测试。

        foreach (TestObject test in Tests)
        {
              test.RunTest()
        }
        //This is in the TestObject class
        RunTest()
        {
             if (failure)
             {
                 //Want to be able to run RunTest() again without interrupting the foreach loop.
             }
        }

你们太喜欢代码了...

for (var tryCount = 0; tryCount < 3; tryCount++)
    if (test.RunTest())
        break;

...哦，我想到了一个更短的版本...但它不是那么干净...

for (var tryCount = 0; !test.RunTest() && tryCount < 3; tryCount++);

如果你想重用那么像这样......

static bool RunTest(Func<bool> testCase, int maxRetry)
{
    for (var tryCount = 0; tryCount < maxRetry; tryCount++)
        if (testCase())
            return true;
    return false;
}

// usage
var testResult = RunTest(test.RunTest, 3);

// or even...
var testResult = RunTest(
    {
        try {
            return test.RunTest();
        } catch (Exception ex) {
            Debug.WriteLine(ex);
            return false;
        }
    }, 3);
