string.Contains 结果在 => HRESULT: 0x80070002

Question

Sitrep：我有一个解析函数，可以将数组中的多个文本解析为值。我连续多次进行相同类型的解析，前 3 次有效，而后两次在我尝试构建时在 Xamarin 中引发错误。我已经经历了好几次，但无法弄清楚它们有什么问题。

错误：

System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
at Microsoft.Samples.Debugging.CorDebug.NativeApi.ICorDebug.CreateProcess(String lpApplicationName, String lpCommandLine, SECURITY_ATTRIBUTES lpProcessAttributes, SECURITY_ATTRIBUTES lpThreadAttributes, Int32 bInheritHandles, UInt32 dwCreationFlags, IntPtr lpEnvironment, String lpCurrentDirectory, STARTUPINFO lpStartupInfo, PROCESS_INFORMATION lpProcessInformation, CorDebugCreateProcessFlags debuggingFlags, ICorDebugProcess& ppProcess)

现在我已经查看了这个错误，并且我已经阅读了它，但是我对它的理解还不够，无法做出任何解释。对我来说，Xamarin 似乎找不到调试构建所需的文件，因此我尝试在 Xamarin 上进行修复安装，但这没有帮助。

代码

for (int i = 0; i < lines.Length; i++) {
        string s = lines[i];
        bool p;
// Some other parsing stuff

        else if (s.Contains("Melee:")) {
            int myMelee;
            p = int.TryParse(s.Replace("Melee:", "").Trim(), out myMelee);
            currentMek.melee = myMelee;
            mekMelee.Value = currentMek.melee;
        }
        else if (s.Contains("Guns:")) {
            int myGuns;
            p = int.TryParse(s.Replace("Guns:", "").Trim(), out myGuns);
            currentMek.guns = myGuns;
            mekGuns.Value = currentMek.guns;
        }
        else if (s.Contains("Cannons:")) {
            int myCannons;
            p = int.TryParse(s.Replace("Cannons:", "").Trim(), out myCannons);
            currentMek.cannons = myCannons;
            mekCannons.Value = currentMek.cannons;
        }
        //causing problems from here down
        else if (s.Contains("Missiles:")) {
            int myMissiles;
            p = int.TryParse(s.Replace("Missiles:", "").Trim(), out myMissiles);
            currentMek.missiles = myMissiles;
            mekMissiles.Value = currentMek.missiles;
        }
        else if (s.Contains("Rockets:")) {
            int myRockets;
            p = int.TryParse(s.Replace("Rockets:", "").Trim(), out myRockets);
            currentMek.rockets = myRockets;
            mekRockets.Value = currentMek.rockets;
        }
}

如果我删除或注释掉最后两个 if else，一切都很好。这是为什么呢？

我认为您的数组中有一些错误，请尝试检查您要查找的行是否实际上在您的数组中，错误可能是 ArrayOutOfIndex ，因为 Visual Studio 多次返回错误错误大多在 VS2012 中。等待您的回复。
