正确的C＃类方法使用dllimport从DLL获取数据 [英] Correct C# class method to get data from DLL using dllimport

问题描述

I am using DLLImport in a C# project for the first time.  I have not found the right way to specify a class method to get data from the DLL.  Here is my code; the public void CallDLL is not correct.  Any help with the right method call would be very appreciated.  

    internal static class NativeMethods
    {
        [DllImport("SMA_03_Process.dll", EntryPoint="S0Process")]
        public static extern int ReturnVal(int a, int b);
    }

        public void CallDLL
        {
            int Value;
            Value = S0Process;
        }
    }

我的尝试：



具有不同结构的其他方法标题，其中没有一个是正确的。

What I have tried:

Other method headers with different constructions, none of which have been correct.

推荐答案

public void CallDLL()
{
    int a = 2; // example
    int b = 3; // example

    int Value = NativeMethods.ReturnVal(a, b);

    // ...
}

到目前为止一切顺利，但编译器回复：

So far so good, but the compiler responds:

A get or set accessor expected

get访问者的调用在哪里？

Where does the call for the get accessor go?
