用c#完成的querysmstatusa(华为api)_移动短信技术

public static extern int QuerySMStatusA(
uint SM_ID,
char OrgTON,
char OrgNPI,
string OrgAddr,
char[] DestTON,
char[] DestNPI,
string DestAddr,
string Final_date,
out  uint   SM_Status,
out uint  Error_Code);
……
char[]  DestTON={0};
char[] DestNPI={0};
string Final_date=””;
string DestAddr=””;
uint Sm_Status,Error_Code;

int i=QuerySMStatusA(sm_id,2,1,”999999″,DestTON,DestNPI, DestAddr,Final_date,out  Sm_Status, out Error_Code);

i,SM_Status,Error_Code 能返回正确的值.
