在64位系统上使用32位dll显示0x8007000B错误 [英] Using 32-bit dll on 64-bit system shows 0x8007000B Error

问题描述

我必须在我的应用程序中使用第三方DLL。 DLL是32位，我使用的系统是64位操作系统。

我已经在我的DotNet应用程序（framework-4.5）中导入了32位DLL，如下所示：

  [DllImport（Sample.dll，
 EntryPoint =Add，
 CharSet = CharSet.Ansi，
 CallingConvention = CallingConvention.StdCall）] 
 public static extern int Add（int iA，int iB）; 
  

在IIS 7.5中 - 我已将启用32位应用程序设置为 p>

并尝试将编译器管理器设置为 - X86，x64和任何CPU。

但是所有的尝试结果与

相同的错误

 尝试加载格式不正确的程序。 （来自HRESULT的异常：0x8007000B）
  

如何解决此问题......

解决方案

我遇到了这个问题，当我在64位机器上运行32位dll和使用DllImport方法时，忘记安装适当的可再发行库，为我所打电话。我需要安装可视化c + +可重新分发的时候，一个被调用的库有依赖于这一点，我还需要安装英特尔Visual Fortran可再发行组件 - 当从.NET库调用Fortran函数。

I have to use a third party DLL in my application. The DLL is a 32-bit and the system I am using is 64-bit OS.

I have Imported the 32-bit DLL in my DotNet application (framework-4.5) as below

 [DllImport("Sample.dll",
  EntryPoint = "Add",
  CharSet = CharSet.Ansi,
  CallingConvention = CallingConvention.StdCall)]
  public static extern int Add(int iA, int iB);

In IIS 7.5 - I have set "Enable 32-bit Application" as "True".

And also tried setting the Compiler Manager as - X86, x64 and Any CPU.

But all the attempt results in same Error as

 An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

How to resolve this Issue......

解决方案

I have experienced this problem both when I was running a 32-bit dll on a 64-bit machine and when using the DllImport method and forgetting to install the appropriate redistributable library for what I was calling. I've needed to install the visual c++ redistributable on occasion when a called library had a dependency on that and I've also needed to install the Intel Visual Fortran redistributable - when calling a Fortran function from a .NET library.
