我有一個C#.Net腳本,用於將文件移動到目錄並在文件名已存在時向文件名添加增量。它完全在我的包之一,但我把它抄了另一個包,它失敗,出現以下錯誤信息:FileInfo.MoveTo在SSIS包中的C#.Net腳本中生成錯誤
DTS SCript Task has encounter an exception in user code:
Project name: ST_<blablabla>
Exception has been thrown by the target of an invocation.
at System.RuntimeMethodHandle.InvokeMethod(Object target,Object[] arguments,Signature si, Boolean constructor)
at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] paramters, Object[] arguments)

下面是實際的代碼:
public void Main()
{
// TODO: Add your code here
string fileName = Dts.Variables["LoopFiles"].Value.ToString();
System.IO.FileInfo file2 = new System.IO.FileInfo(Dts.Variables["FolderPath"].Value + fileName);
int count = 1;
string fullPath =Dts.Variables["FolderPath"].Value.ToString() + Dts.Variables["LoopFiles"].Value.ToString();
string fileNameOnly = Path.GetFileNameWithoutExtension(fullPath);
string extension = Path.GetExtension(fullPath);
string path = Path.GetDirectoryName(fullPath);
string newFullPath = fullPath;
while (File.Exists(newFullPath))
{
string tempFileName = string.Format("{0}({1})", fileNameOnly, count++);
newFullPath = Path.Combine(path, tempFileName + extension);
}
DialogResult button3 = MessageBox.Show(file2.ToString());
file2.MoveTo(newFullPath);
DialogResult button5 = MessageBox.Show("Last Step");
Dts.TaskResult = (int)ScriptResults.Success;
}
作爲一個說明,BUTTON3持久性有機污染物在運行時應該像例行程序那樣運行,但在顯示按鈕5之前會出現錯誤。任何關於爲什麼這種困難的信息都會有相當大的幫助。
謝謝!
啊,完美!原來我在源路徑中使用了錯誤的變量。非常感謝,我計劃在MessageBoxes上使用你的建議。 – Jack 2014-09-03 12:03:59
