无法调用函数，未命中断点，- 无法从 mscorlib 加载程序集

Question

问题

我有一个方法，可以调用但永远不会执行。

调用 'CreateHomeDrive' 的行如下所示：

FileInterface.HomeDriveCreation.CreateHomeDrive("my_domain","admin_user","admin_pwd", document.UserName);

成功到达该行，相应的中断指针停止

应该到达但从未到达以下 Break 指针。
只有 1 个方法引用此函数：

public class HomeDriveCreation
{
    public static void CreateHomeDrive(string domainName, string adminUser, string adminPassword, string userNameToCreate)
        {
            {/*Break pint here is never reached!*/ }
            // method logic here...
        }
}

知道为什么永远无法达到此代码吗？中断指针位于函数的第一行，因此根据我的理解，应该始终到达此中断标记。

确实抛出了一个错误，这对我没有帮助：

One or more errors occurred. 
(Could not load type 'System.Security.Principal.WindowsImpersonationContext' 
from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=/*private?*/'.)

项目结构

项目结构如下所示：

FileInterface 是一个 .net Framework class 库，
调用 FileInterface.HomeDriveCreation 的 JiraBackgroundTasks 是一个 .net core 3.5 class 库。

添加了对 System.Security 的引用

具体class应该叫什么

要调用的代码源自 Microsoft 模拟参考 https://docs.microsoft.com/en-us/dotnet/api/system.security.principal.windowsidentity.impersonate?redirectedfrom=MSDN&view=netframework-4.8#System_Security_Principal_WindowsIdentity_Impersonate_System_IntPtr_ 这是完整的 class:

Answer 1

WindowsImpersonationContext 特定于 .Net Framework。请注意您发布的文章中的“适用于”部分。

对于 .Net Core，您可以使用 WindowsIdentity.RunImpersonated .

另见 SO: WindowsImpersonationContext & Impersonate() not found in ASP.Core

Answer 2

这种情况下的问题是模拟在 .net core 中的处理方式不同

尽管该项目是 .net 框架，Visual Studio 无法满足多框架目标解决方案的要求。

有关如何在 .net 核心中模拟的更多信息，请参见此处： https://docs.microsoft.com/en-us/dotnet/api/system.security.principal.windowsidentity.runimpersonated?view=net-5.0

至于模拟文件夹访问权限的具体任务，在这里找到了很好的答案： How to provide user name and password when connecting to a network share（来自 Luke Quinane 的回答）

请记住，当网络位置映射到 Windows 中的不同用户时，这将不起作用。在这种情况下，程序将在内部映射网络驱动器并在使用后对其进行处理。

实施他的 class 然后像这样使用它：

using (new NetworkConnection(@"\server\Data\Home", cred))
{
    string path = $@"\server\Data\Home\testuserfolder";
    string domainName = "domain.com";
    string userNameToCreate = "testuser";
    Directory.CreateDirectory(path);
    SetFullPermission(path, userNameToCreate);
}
