从接收到的数据存储过程填充自定义 C# 对象

public class User
{
   public string FirstName { get; set; }
   public string LastName { get; set; }
}

public class Address
{
    public string City { get; set; }
    public string Country { get; set; }
}


/*
 * There are 2 c# objects i have shown 
 * There is a stored procedure in my application which
 * returns data for both objects simultaneously 
 * eg 
 * select FirstName, LasteName from Users where something="xyz"
 * select City,Country from Locations where something="xyz"
 * 
 * both queries are run by single procedure 
 * Now how can i fill both objects with from that stored procedure in asp.net using c#

使用 ADO.NET，在执行带有参数的 SP 的 SqlCommand 对象上打开 SqlDataReader。使用 SqlDataReader.NextResult 方法获取第二个结果集。

基本上：

SqlConnection cn = new SqlConnection("<ConnectionString>");
cn.Open();

SqlCommand Cmd = new SqlCommand("<StoredProcedureName>", cn);
Cmd.CommandType = System.Data.CommandType.StoredProcedure;

SqlDataReader dr = Cmd.ExecuteReader(CommandBehavior.CloseConnection);

while ( dr.Read() ) {
    // populate your first object
}

dr.NextResult();

while ( dr.Read() ) {
    // populate your second object
}

dr.Close();
