使用未分配的局部变量的“SHELLEXECUTEINFO”

大家上了车调试我用C＃应用程序，这是错误的错误：使用未分配的局部变量的“SHELLEXECUTEINFO”

使用未分配的局部变量的“SHELLEXECUTEINFO”

这是错误行CBSIZE = Marshal.SizeOf（SHELLEXECUTEINFO），

我不知道为什么我收到此错误或如何纠正它。

遗憾的坏显示我新我在这里，我不知道如何编辑我的问题.... – user3328787

你的初始化器使用变量在初始化之前。初始化程序常见的鸡与鸡问题。你可以只使用其他重载：

Form1.SHELLEXECUTEINFO sHELLEXECUTEINFO = new Form1.SHELLEXECUTEINFO() 
    { 
     cbSize = Marshal.SizeOf(typeof(Form1.SHELLEXECUTEINFO)), 
     lpFile = pWOLocation, 
     // etc... 
    };

或者更一般的解决方案：

Form1.SHELLEXECUTEINFO sHELLEXECUTEINFO = new Form1.SHELLEXECUTEINFO() 
    { 
     lpFile = pWOLocation, 
     // etc... 
    }; 
    sHELLEXECUTEINFO.cbSize = Marshal.SizeOf(sHELLEXECUTEINFO));

叫人BTW检查你的代码。

C＃编译器不允许使用未初始化的变量。看起来你在使用它之前未初始化的变量sHELLEXECUTEINFO。

这是快速的答案感谢您的快速。但是如何初始化它？ – user3328787

@ user3328787但请重新格式化您的代码。所以我们可以帮助你更好。 –

现在我重新格式化我的代码，我发现的编辑按钮：d – user3328787
