比较两个文件，设置产品版本 [英] Compare Two file,Set Product version

问题描述

嗨。



i有框架需要将本地的dll文件（模块）与服务器中的相应文件进行比较，如果新版本可用，请下载< br $>


i有问题，当我用我的服务下载文件接收文件（1024字节1024字节和合并字节来创建文件）时，我无法设置产品版本文件编程。



我可以用C＃设置文件的产品版本吗？



你知道其他吗？方式二比较两个文件（否则容量因为不正确）？



请帮帮我。



谢谢，

推荐答案

我认为你不能一次更改程序集版本它已被编译。虽然你可以比较两个单独的dll文件的汇编版本。

I don't think you can change the assembly version once it's been compiled. Although you can compare the assembly versions of two separate dll files.

string existingAssemblyPath = "foo\\bar.dll";
System.Reflection.Assembly existingAssemby = System.Reflection.Assembly.Load(existingAssemblyPath);
Version existingVersion = existingAssemby.GetName().Version;

byte[] downloadedBytes; //assign download file bytes
System.Reflection.Assembly newAssemby = System.Reflection.Assembly.Load(downloadedBytes);
Version newVersion = newAssemby.GetName().Version;

if (newVersion > existingVersion)
{
  //save file
}

这是我的错，如果我完全下载文件，产品版本就可以了。

对不起

it was my wrong , if i download file completely ,product version is with it.
I'm sorry
