Asp.Net添加信息的几种方法

第一种

DAL层
public static void AddUserMessage(string name,string pwd)
{
try
{
StringBuilder strSql = new StringBuilder();
strSql.Append("insert into My_UserMessage(");
strSql.Append("uname,password)");
strSql.Append(" values (");
strSql.Append("'" + name + "',");
strSql.Append("'" + pwd + "'");
strSql.Append(")");
DBHelper.ExecuteCommand(strSql.ToString());
}
catch (Exception ex)
{
throw ex;
}
}

BLL层
public static void AddUserMessage(string name, string pwd)
{
UserService.AddUserMessage(name,pwd);
}

Web层
string Uname = this.txtUsername.Text.Trim();
string Password = this.txtPWD.Text.Trim();
UserManager.AddUserMessage(Uname, Password);

第二种

DAL层
public static int AddUser(UserMessage message)
{
string sql ="INSERT My_UserMessage (uname, password) VALUES (@uname, @password)";
sql += " ; SELECT @@IDENTITY";
try
{
SqlParameter[] para = new SqlParameter[]
{
new SqlParameter("@uname", message.Uname),
new SqlParameter("@password", message.Password)
};
int newId = DBHelper.GetScalar(sql, para);
return newId;
}
catch (Exception e)
{
Console.WriteLine(e.Message);
throw e;
}
}

BLL层
public static void AddUser(UserMessage u)
{
UserService.AddUser(u);
}
Web层
UserMessage u = new UserMessage();
u.Uname = this.txtUsername.Text.Trim();
u.Password = this.txtPWD.Text.Trim();
UserManager.AddUser(u);

第三种

DAL层

}
catch (Exception e)
{

throw e;
}
}

BLL层
public static void AddUser(UserMessage message)
{
UserService.AddUser(message);
}
Web层
UserMessage u = new UserMessage();

*********************************************************************************************************************************************
第四种

DAL层
public static void AddUser(UserMessage message)
{
try
{
StringBuilder strSql = new StringBuilder();
strSql.Append("insert into My_UserMessage(");
strSql.Append("uname,password)");
strSql.Append(" values (");
strSql.Append("@uname,@password)");

SqlParameter[] parameters =
{
new SqlParameter("@uname", SqlDbType.VarChar,100),
new SqlParameter("@password", SqlDbType.VarChar,100)
};
parameters[0].Value = message.Uname;
parameters[1].Value = message.Password;

DBHelper.GetScalar(strSql.ToString(), parameters);
}
catch (Exception ex)
{

throw e;
}
}

BLL层
public static void AddUser(UserMessage message)
{
UserService.AddUser(message);
}
Web层
UserMessage u = new UserMessage();
