C＃获取非托管的DLL版本 [英] C# getting version of unmanaged dll

问题描述

我打电话是从我管理的C＃代码的非托管的dll，想检查我打电话正确的版本。

I'm calling an unmanaged dll from my managed c# code and wanted to check I'm calling the right version.

我试图加载程序集（以再获取资源文件，然后获取版本）的代码是：
cur_version = Assembly.LoadFile（ X：\Workspace\yreceipts_pos\yRprintProcessor\Debug\yRprintProcessor.dll）;
它的失败，因为这个错误的：
该模块应包含一个程序集清单。 （异常来自HRESULT：0x80131018）

The code I'm trying to load the assembly (to then get the resource file and then get the version) is: cur_version = Assembly.LoadFile("X:\Workspace\yreceipts_pos\yRprintProcessor\Debug\yRprintProcessor.dll"); It's failing because of this error: The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018)

有谁知道如何解决这个问题，或有更好的方法来检查非托管DLL的版本从托管的C＃代码？

Does anyone know how to get around this or have a better way to check the version of an unmanaged dll from managed c# code?

在提前，
理查德

Thanks in advance, Richard

推荐答案

作为感谢通过logicnp陈述;的的Assembly.Load仅用于管理组件。要确定您可以使用System.Diagnostics.FileVersionInfo.GetVersionInfo（文件名）和加载并调用DLL中您可以参考这些文章非托管程序任何版本-ED文件的版本：

As stated by logicnp; the Assembly.Load is for managed assemblies only. To determine the version of any version-ed file you can use System.Diagnostics.FileVersionInfo.GetVersionInfo(filename) and to load and call unmanaged procedures in DLLs you can refer to these articles:
