C#调用DLL的问题

[sjfujiang]

char* strParameters[4];
strParameters[0] = (char*)malloc(256);
strParameters[1] = (char*)malloc(256);
strcpy(strParameters[0],"F:\\abc\\");
strcpy(strParameters[1],"F:\\abc\\");
int nRet = m_InitConnect(strParameters,4);


以上是在C++中调用m_InitConnect DLL动态链接库中的m_InitConnect这个方法.
如果在C#中该如何写?

char* strParameters[4] 要转成什么?

char* strParameters[4] 要转成string[]，

[stonespace]

[DllImport("xxxx.dll", CharSet = CharSet.Ansi)]
public static extern int m_InitConnect(String[] strParameters, int nSize);

[sjfujiang]

string[] 貌似不行....

[sjfujiang]

string str = "F:\\abc\\";
string[] arrstr=new string[4];
arrstr[0] = str;
arrstr[1] = str;
int n = 4;
int nRet = InitConnect(ref arrstr,n);
这样转的,但好像不太对.

string[]是可以的，没有ref
int nRet = InitConnect(arrstr,n);

[wangchangming]

byte[]

[bdsutx]

转成stringbuilder
定义的时候就是 stringbuilder aa=new stringbuilder();

[stonespace]

不要ref，

int nRet = InitConnect(arrstr,n);


[Quote=引用 4 楼 的回复:]

string str = "F:\\abc\\";
string[] arrstr=new string[4];
arrstr[0] = str;
arrstr[1] = str;
int n = 4;
int nRet = InitConnect(ref arrst……
