我在Windows窗体应用程序中使用TypeInitializationException时遇到问题，当使用模拟打开SQLconnection时（当模拟删除一切正常时），我不知道如何解决该问题。
这是StackTrace：

v System.Data.Linq.SqlClient.SqlProvider.System.Data.Linq.Provider.IProvider.Initialize(IDataServices dataServices, Object connection)
v System.Data.Linq.DataContext.Init(Object connection, MappingSource mapping)

这是innerException的StackTrace

这是我的模拟代码：
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
public class Impersonation : IDisposable
{
private readonly SafeTokenHandle _handle;
private readonly WindowsImpersonationContext _context;
const int LOGON32_LOGON_NEW_CREDENTIALS = 9;
public Impersonation(string domain, string username, string password)
{
var ok = LogonUser(username, domain, password,
LOGON32_LOGON_NEW_CREDENTIALS, 0, out this._handle);
if (!ok)
{
var errorCode = Marshal.GetLastWin32Error();
throw new ApplicationException(string.Format("Could not impersonate the elevated user. LogonUser returned error code {0}.", errorCode));
}
this._context = WindowsIdentity.Impersonate(this._handle.DangerousGetHandle());
}
public void Dispose()
{
this._context.Dispose();
this._handle.Dispose();
}
[DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
private static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, out SafeTokenHandle phToken);
public sealed class SafeTokenHandle : SafeHandleZeroOrMinusOneIsInvalid
{
private SafeTokenHandle()
: base(true) { }
[DllImport("kernel32.dll")]
[ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)]
[SuppressUnmanagedCodeSecurity]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool CloseHandle(IntPtr handle);
protected override bool ReleaseHandle()
{
return CloseHandle(handle);
}
}
}
问题是-我之前在不同的ap中使用了该模拟代码，并且一切正常。我很拼命，有帮助吗？谢谢。
这是连接字符串：
private readonly string _connectionString = "data source = xxx\\xxx; initial catalog = xxx; integrated security=True; MultipleActiveResultSets=True";
这里是开场白：
using (UnitOfWork frt = new UnitOfWork(_connectionString))
{
_outCalls.DownloadOutCalls(frt, _orders.ReturnSetOfNumbers());
}
UnitOfWork（您在这里获得TypeInitializationException）：
public class UnitOfWork : IDisposable
{
....repositories...
private readonly DataContext _context;
public UnitOfWork(string connectionString)
{
_context = new DataContext(connectionString);
....repositories...
}
public void Dispose()
{
Dispose(true);
}
protected virtual void Dispose(bool disposing)
{
if (disposing)
{
if (_context != null)
_context.Dispose();
}
}
}
内部异常是FileNotFoundException，但似乎引用了.exe本身-我不理解这一点。
编辑-2018年10月8日 我发现.exe在我的桌面上但不在共享Intranet驱动器上时，一切正常。但是模拟帐户具有与我的帐户相同的权利。 如前所述，我有一个使用相同模拟代码，相同连接字符串的其他应用程序，并且所有内容均可在我的台式机和共享驱动器上使用。
编辑-8.10.2018-11:00 所以它崩溃了... System.Diagnostics.FileVersionInfo.GetVersionInfo（pathToExe），
答案 0 :(得分：0)
所以... 一段时间后，一个解决方案。 似乎在--- System.Diagnostics.FileVersionInfo.GetVersionInfo（pathToExe）中出现错误，因此将我的模拟调用从程序移到了工作单元。以此方式进行更改：
public class UnitOfWork : IDisposable
{
public IOrderRepository Orders { get; }
public ICallRepository OutCalls { get; }
public ILoginRepository Login { get; }
private readonly DataContext _context;
public UnitOfWork(string connectionString)
{
_context = new DataContext(new SqlConnection());
using (new Impersonation("domain", "user", "password"))
_context.Connection.ConnectionString = connectionString;
Orders = new OrderRepository(_context);
OutCalls = new CallRepository(_context);
Login = new LoginRepository(_context);
}
public void Dispose()
{
Dispose(true);
}
protected virtual void Dispose(bool disposing)
{
if (disposing)
{
if (_context != null)
_context.Dispose();
}
}
}
