vb shell函数在c#的转换

vb shell:

Private Sub AddBarcodeImages(ByVal DTab As DataTable)
If Not DTab Is Nothing Then DTab.Columns.Add("BCIMAGE", Type.GetType("System.Byte[]")) Dim r As DataRow
For Each r In DTab.Rows Try
Dim BatchNo As String = CStr(r.Item("Operator2")).Trim
Dim sFileName As String = "C:\TEMP\" & BatchNo & ".jpg" Shell("Barcode.exe " & BatchNo & "", AppWinStyle.NormalFocus, True) Dim fs As IO.FileStream = New IO.FileStream(sFileName, IO.FileMode.Open)
Dim fi As IO.FileInfo = New IO.FileInfo(sFileName)
Dim fl As Long = fi.Length
Dim lung As Integer = Convert.ToInt32(fl)
Dim imgBytes As Byte() = New Byte(lung - ) {}
fs.Read(imgBytes, , lung)
fs.Close()
r.Item("BCIMAGE") = imgBytes Dim f As IO.File
Try
f.Delete(sFileName)
Catch ex As Exception
Console.WriteLine(ex.ToString)
End Try Catch ex As Exception
'MessageBox.Show(ex.ToString)
End Try
Next
End If
End Sub

c# Process线程:

private DataTable getReportData()
{
