在Visual Studio 2013中的sqlite錯誤消息system.io.fileloadexception

我是一個家庭學校的代碼作家，不是很技術。我試圖使用VB在Visual Studio 2013中使用sqlite訪問s3db文件。我不斷收到此錯誤信息「類型‘System.IO.FileLoadException’未處理的異常發生在sqlite.exe在Visual Studio 2013中的sqlite錯誤消息system.io.fileloadexception

其他信息：混合模式組件對運行時的版本‘V2.0.50727’建成並不能加載到4.0運行時沒有額外的配置信息。「

代碼如下，調試器指向loadpropertydata（）

進口System.Data.SQLite 公共類listboxpropertydata

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load 

    loadpropertydata() 

End Sub 
Public Sub loadpropertydata() 
    Dim connectionString As String = "data source=c:\users\andy\documents\a la mode\database\spectrum.s3db" 
    Dim mSQL As String = "select AD_ADDR1, AD_ADDR2, PR_SALEPR1, SC_SOURCE1, SC_SOURCE2, FN_CONC1,FN_CONC2, DT_SALTIM1, LC_LOCAT1, RG_RIGHTS, ST_SITSIZE, ST_SITEVW,DA_DESAPL1, DA_CONSTQL, AG_AGYRBLT, AG_COND1, RM_TOTAL, RM_BED,RM_BATH, SF_GLA, BM_BSM1, BM_BSM2, FU_FUNCTUT, HC_HTCOOL, EE_EFFIC1,CR_GARPRK1, PF_PORPAT1, BL_BLANK1, BL_BLANK2, BL_BLANK3, HS_PRIOR1,HS_PRIOR2, HS_PRIOR3, HS_DSDATE from TOTALFormSource" 
    Dim dt As DataTable = Nothing 
    Dim ds As New DataSet 

    Try 
     Using con As New SQLiteConnection(connectionString) 
      Using cmd As New SQLiteCommand(mSQL, con) 
       con.Open() 
       Using da As New SQLiteDataAdapter(cmd) 
        da.Fill(ds) 
        dt = ds.Tables(0) 
       End Using 
      End Using 
     End Using 

     listboxsqlresults.valuemember = "PropertyGrid" 
     listboxsqlresults.displaymember = "Address" 
     listboxsqlresults.datasource = dt 
    Catch ex As Exception 
     MsgBox(ex.Message) 
    End Try 
End Sub
