c# - DllImport - C 类型到 .NET 类型

Question

我有dll函数

DLLExport int PatchSomething(char*, char*, DWORD, unsigned char*, unsigned short int);

但无法将参数完全传递给.NET

F#:

模块 RNInvoke

open System
open System.Runtime.InteropServices
open Microsoft.FSharp.NativeInterop
open Microsoft.FSharp.Math

module Native =
    [<System.Runtime.InteropServices.DllImport("DesuDLL.dll",EntryPoint="add")>]
    extern int PatchSomething(char*, char*, DWORD, unsigned char*, unsigned short int);

或 C#

[DllImport("DesuDLL.dll")]
private static extern int PatchSomething(char*, char*, DWORD, unsigned char*, unsigned short int);

unsigned char* 和 unsigned short int 错误

Answer 1

尝试这样的事情:

[DllImport("DesuDLL.dll")]
private static extern int PatchSomething(string a,string b,uint c,string d,ushort e);

您可能还需要将 CharSet = Auto 放入属性中。我唯一关心的是 unsigned char 指针。
