移动文件，AX2012 [英] Move a file, AX2012

问题描述

我正在尝试移动文件，没有什么聪明的方法。

I'm trying to move a file, nothing clever.

AX WONDERS博客。

这样做的原因是，当使用在服务器上运行的AX类时，异常永远不会返回到客户端，因此无法正确处理....该操作不会陷入异常： ：CRLError异常

The reason for this is that when using an AX class that runs on the server, the exception never comes back to the client and therefore cannot be handled correctly.... the operation will not fall into the Exception::CRLError exception

例如，如果源文件由MSWord打开，则会在 fileLocked中引发异常。

If the source file is opened by MSWord, for example, an exception is thrown in the fileLocked method, which is both infuriating yet amusing.

任何建议都非常欢迎！

某些代码：

server static void moveFile(str fileName, str newFileName)
{
    #File
    Set                 permissionSet;
    ;

    permissionSet =  new Set(Types::Class);
    //permissionSet.add(new FileIOPermission(fileName,#io_write));
    permissionSet.add(new FileIOPermission('',#io_write));
    permissionSet.add(new InteropPermission(InteropKind::ClrInterop));

    CodeAccessPermission::assertMultiple(permissionSet);

    if (isRunningOnServer()) 
    { 
        if (WinAPIServer::fileExists(newFileName))
            WinAPIServer::deleteFile(newFileName);
        WinAPIServer::copyFile(fileName, newFileName);
        if (!WinAPIServer::fileLocked(fileName))
            WinAPIServer::deleteFile(fileName);
    }
    else
    {
        if (WinApi::fileExists(newFileName))
            WinApi::deleteFile(newFileName);
        WinAPI::copyFile(fileName, newFileName);
        if (!WinAPI::fileLocked(fileName))
            WinAPI::deleteFile(fileName);
    }
    //System.IO.File::Move(fileName, newFileName);

    CodeAccessPermission::revertAssert();
}

错误注册表：

System.IO.IOException: The process cannot access the file 'M:\Interfaces\Prod\ImportacionClientes\Direcciones\XXXXXXAD_20130711_1136.TXT' because it is being used by another process.

推荐答案

我会去

 System.IO.File::Move(fileName, newFileName);

而不是变得聪明。
认为 newFileName 的先前存在是错误。

instead of being to clever. Consider the prior existence of the newFileName an error.

不要使用<$ c服务器或批处理上下文中的$ c> WinAPI 文件方法（已检查）。

同时使用 WinAPI 和 WinAPIServer 太痛苦了，直接使用.Net方法。

Don't use the WinAPI file methods in a server or batch context (you checked that).
Using both WinAPI and WinAPIServer is just too painful, go straight for the .Net methods.

很有可能fileLocked 错误。
