C语言DLL如何接收Dictionary<string, string>参数

C语言不直接支持Dictionary<string, string>参数类型,但可以通过以下步骤实现:
1. 在C#中定义一个带有Dictionary<string, string>参数的函数,并将其导出为DLL。
```csharp
public static class MyDll
{
[DllImport("MyDll.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern void MyFunction(Dictionary<string, string> dictionary);
}
```
2. 在C++中引用该DLL,并使用C++/CLI(Common Language Infrastructure)将C++代码与C#代码连接起来。
```cpp
#include <cliext/adapter>
using namespace System::Collections::Generic;
void MyFunctionWrapper(cliext::dictionary<std::string, std::string>& dictionary)
{
// 在此处实现C++调用C#函数的逻辑
}
extern "C" __declspec(dllexport) void __stdcall MyFunction(Dictionary<std::string, std::string>^ dictionary)
{
cliext::dictionary<std::string, std::string> adapter;
adapter = cliext::adapt(dictionary);
MyFunctionWrapper(adapter);
}
```
3. 在C++中调用MyFunction函数,并将Dictionary<string, string>类型的参数传递给它。
```cpp
#include <map>
#include <string>
using namespace std;
int main()
{
map<string, string> dictionary;
dictionary["key1"] = "value1";
dictionary["key2"] = "value2";
DictionaryAdapter adapter(dictionary);
MyFunction(adapter.ToDictionary());
return 0;
}
```
注意:上述代码只是示例,实际应用中可能需要进行更多的异常处理和类型转换。
