Error: 0x1 at XX: Exception has been thrown by the target of an invocation

Question

I am trying to copy files from an FTP server to a local drive using C# Task script in SSIS. The script ran well in SQL Studio 2008 R2, but there was a version update to 2016 usi

Answer 1

The Error may be cause by a permission issue for reading from UNC path or writing to local file, try adding a try ... catch block to read the real exception since the following exception is generic:

Exception has been thrown by the target of an invocation

Try using the following code:

public void Main()

{
try{

        string fileDate = string.Format("{0:d4}", DateTime.Today.Year).ToString() + string.Format("{0:d2}", DateTime.Today.Month).ToString() + "13";
        string src1FileName = @"\\Slocation03\Reports\SSI224-069_" + fileDate + ".txt";
        string des1FileName = @"\\Slocation03\Reports\EContacts\SSI224-069.txt";

        string src2FileName = @"\\Slocation03\Reports\SSI224-071_" + fileDate + ".txt";
        string des2FileName = @"\\Slocation03\Reports\EContacts\SSI224-071.txt";

        if (File.Exists(src1FileName))
       {
                File.Copy(src1FileName, des1FileName, true);
        }

       if (File.Exists(src2FileName))
        {
            File.Copy(src2FileName, des2FileName, true);
        }

        Dts.TaskResult = (int)ScriptResults.Success;

    }catch(Exception ex){

        Dts.FireError(0,"An error occured", ex.Message,String.Empty, 0);
        Dts.TaskResult = (int)ScriptResult.Failure;

    }

}
