我正在尝试使用 SSIS 中的 C# 任务脚本将文件从 FTP 服务器复制到本地驱动器。该脚本在 SQL Studio 2008 R2 中运行良好,但使用 SQL SSDT (SQL Server Data Tools) 2015 将版本更新到 2016,当我第一次执行该脚本时它运行正常,但后来抛出以下错误:
Error: 0x1 at 3-Copy and rename EC Files: Exception has been thrown by the target of an invocation. Task failed: 3-Copy and rename EC Files
看了几个帖子,得知答主通过添加dll版本12.0.0的引用,并将Target Framework改为.Net Framework 4.5,解决了问题。
目前我的目标框架是 .Net Framework 4.5。
我怎样才能停止收到这个错误?
在应用程序中的什么地方可以找到执行该更改的 dll 引用?
非常感谢您的帮助。
我的C#程序如下图所示:
using System;
using System.IO;
namespace ST_d70bfcb8d94b40849d1d525fe3731f14.csproj
{
[Microsoft.SqlServer
.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
{
#region VSTA generated code
enum ScriptResults
{
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
};
#endregion
public void Main()
{
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;
}
}
}
最佳答案
错误可能是由从 UNC 路径读取或写入本地文件的权限问题引起的,尝试添加一个 try ... catch block 来读取真正的异常,因为以下异常是通用的:
Exception has been thrown by the target of an invocation
尝试使用以下代码:
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;
}
}
