Answer 1

您可以找到 vjsnativ.dll 并将其复制到您的应用程序目录，或者您可以在调用任何 J# 代码之前添加此代码。

// This problem started with .NET 4
if (Environment.Version.Major >= 4)
{
    string dllpath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), @"..\Microsoft.NET\Framework\v2.0.50727");
    dllpath = Path.GetFullPath(dllpath);
    LoadLibrary(Path.Combine(dllpath, "vjsnativ.dll"));
}
// J# code should work now
