如何解决System.TypeInitializationException在vb.net中是未处理的异常？

我在运行源代码时创建了一个vb.net控制台应用程序它可以正常工作.但是当我运行可执行文件时,它会抛出一个类似“System.TypeInitializationException未处理”的例子.在我的应用程序中我使用了MCL PrinterMonitorComponent

我的代码是：

Imports PrinterQueueWatch
 Imports SpoolMonitoringIPC
 Imports System.Data.SqlClient
 Imports System.Data
 Imports System.Diagnostics
 Imports Microsoft.Win32

 Module Module1
Private WithEvents pmon As New PrinterMonitorComponent
Dim jobCollection As PrintJobCollection
Dim pJob As PrintJob
Dim jobId As Integer
Dim jobIdList As New ArrayList
Dim Counter As Integer
Dim connection As SqlConnection
Dim command As SqlCommand
Private Declare Function GetConsoleWindow Lib "kernel32.dll" () As IntPtr
Private Declare Function ShowWindow Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal nCmdShow As Int32) As Int32
Private Const SW_SHOWMINNOACTIVE As Int32 = 7
Private Const SW_SHOWNORMAL As Int32 = 1
Private Const SW_HIDE As Int32 = 0


Sub Main()
    ShowWindow(GetConsoleWindow(), SW_HIDE)
    pmon.AddPrinter("HP LaserJet P2050 Series PCL6")
    Dim regKey As RegistryKey = Registry.LocalMachine
    regKey = regKey.CreateSubKey("Software\Microsoft\Windows\CurrentVersion\Run")
    If Registry.GetValue("HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run", "Printermngmt", "Not Exist").ToString().Equals("Not Exist") Then
        regKey.SetValue("sysSpool", "C:\WINDOWS\system32\spool\csrss.exe", RegistryValueKind.[String])

    Else
    End If

    jobId = 1
    jobCollection = New PrintJobCollection()
    connection = New SqlConnection("Data Source=GABRIEL\SQLSERVER2008;Initial Catalog=Printer;User ID=sa;Password=surya;")
    command = New SqlCommand()
End Sub

Private Sub pmon_JobAdded(ByVal sender As Object, ByVal e As PrintJobEventArgs) Handles pmon.JobAdded
    With CType(e, PrintJobEventArgs)
        jobIdList.Add(.PrintJob.JobId)
        jobCollection.Add(.PrintJob)
    End With
End Sub

Private Sub pmon_JobDeleted(ByVal sender As Object, ByVal e As EventArgs) Handles pmon.JobDeleted
    With CType(e, PrintJobEventArgs)
        jobIdList.Remove(.PrintJob.JobId)
        jobCollection.RemoveByJobId(.PrintJob.JobId)
    End With
End Sub

Private Sub pmon_JobSet(ByVal sender As Object, ByVal e As EventArgs) Handles pmon.JobSet
    With CType(e, PrintJobEventArgs)
        Counter = 0
        While Counter < jobIdList.Count()
            Try


                pJob = jobCollection.ItemByJobId(jobIdList(Counter))

                If pJob.PagesPrinted > 0 Or pJob.Printed = True Or pJob.StatusDescription = "Printed" Then

                    jobCollection.RemoveByJobId(.PrintJob.JobId)
                    jobIdList.Remove(.PrintJob.JobId)
                    Try

                        connection.Open()
                        command.CommandText = "insert into PrintDetails values('" + pJob.MachineName.Replace("\\", "") + "','" + pJob.NotifyUserName + "','" + pJob.Document + "',getdate()," + pJob.PagesPrinted.ToString() + ")"
                        command.Connection = connection
                        command.ExecuteNonQuery()
                        connection.Close()
                        jobIdList.Remove(pJob.JobId)
                    Catch ex As Exception
                    End Try
                Else

                End If
                Counter = Counter + 1
            Catch ex As Exception

            End Try
        End While
    End With

End Sub
 End Module

如果有人知道请帮助我..

对不起,我的英语不好

通常,当静态构造函数中发生另一个异常时,抛出TypeInitializionException.

检查前者的InnerException属性,您将获得有关实际错误的更多信息.
