The dizziness has been studied for a day, and in order to return structural arrays in the parameter of the function.
Now you share and save time.
Example: /// /// User Information Structure /// Public Struct Tuser {Public String Loginname; Public String LoginPass; Public String TrueName; Public Int Level;
/// /// Get all registered users /// /// Return User Information Structure Public Bool GetUsers (Out Tuser [] g_userinfo) { Userop.tuser [] f_tuser; int curRec = 0; // Initialization Record counter int REC_COUNT = 0; // Computing total record number SQLConnection myconn = new sqlconnection (connectionString); string cmd = "select * from" m_table; // SQL query statement sqlcommand mycmd = new sqlcommand (cmd, myconn); mycmd.connection.open (); // open connection sqlDataReader ADR = null; // Create a data reader try {ADR = mycmd.executeReader (); while ADR.READ ()) {REC_COUNT = 1;} myconn.close (); // Close database connection mycmd.connection.open (); // Open database connection try {adr = mycmd.executeReader (); f_tuser = new Userop.tuser [REC_COUNT]; while (adr.read ()) {f_tuser [curR] .loginname = ADR ["US_LoginName"].
