Question

我正在使用Visual Studio 2010 / .NET 4.0在C＃中创建一个应用程序。对于部分应用程序，我需要压缩文件并使用J＃库。我在导入kernal32.dll时遇到问题。我已经尝试将导入值设置为“kernal32”，“kernal32.dll”和system32文件夹中的绝对路径。我得到的错误如下，相关的源代码低于该值。错误发生在我调用“LoadLibrary（fullPath）;”的行。任何帮助都会被大大挖掘出来！

我从http://blogs.windwardreports.com/davidt/2011/02/calling-j-code-from-net-40.html

的示例中提取了一些代码

尝试kernel32。以下示例通过P / Invoke LoadLibrary页面。

[DllImport("kernel32", SetLastError=true)]
static extern IntPtr LoadLibrary(string lpFileName);

试图从C＃（.NET 4.0）加载kernal32和J＃库并获取kernal32加载错误
