一个C的DLL，如何声明注册到程序，有三个方法，两个已经写了，另一个不知道怎么写，谢谢
如：
function GetDate: Integer; stdcall; external 'WebAccess.dll';
function SetDate(SN: PWideChar): Integer; stdcall; external 'WebAccess.dll';
对应：
[System.Runtime.InteropServices.DllImport("WebAccess.dll", EntryPoint = "GetDate")]
public static extern int GetValidateDate();
[System.Runtime.InteropServices.DllImport("WebAccess.dll", EntryPoint = "SetDate", CharSet = System.Runtime.InteropServices.CharSet.Unicode)]
public static extern int SetValidateDate(string ValidateCode);
那：
function GetInfo(SoftType: PByte; FuncFlags: PDWORD): Integer; stdcall;
这条怎么写？

谢谢

[解决办法]
帮你改了下，试试
[System.Runtime.InteropServices.DllImport("WebAccess.dll", EntryPoint = "GetInfo", CharSet = CharSet.Auto)]
public static extern int GetValidateInfo(ref byte softType, ref int funcFlags);

byte softType = 0;
int funcFlags = 0;
int infoResult = GetValidateInfo(ref softType, ref funcFlags);
