用C#完成的QuerySMStatusA华为API

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.
