如何从SqlDataReader中读取多个结果集？

Question

我有一个SP从我试图返回2的结果，从设定，在我的.cs文件我试图像这样：

dr = cmd.ExecuteReader(); 
while (dr.Read()) 
{ 
    RegistrationDetails regDetails = new RegistrationDetails() 
    { 
    FName = dr["FName"].ToString(), 
    LName = dr["LName"].ToString(), 
    MName = dr["MName"].ToString(), 
    EntityName = dr["EntityName"].ToString(),// in 2nd result set 
    Percentage = dr["Percentage"].ToString()// in 2nd result set 
    }; 
} 

不过我正在一个：

error:IndexOutOfRange {"EntityName"}

在这里，你有一个关于如何处理多个结果集与

static void RetrieveMultipleResults(SqlConnection connection) 
{ 
    using (connection) 
    { 
     SqlCommand command = new SqlCommand(
      "SELECT CategoryID, CategoryName FROM dbo.Categories;" + 
      "SELECT EmployeeID, LastName FROM dbo.Employees", 
      connection); 
     connection.Open(); 

     SqlDataReader reader = command.ExecuteReader(); 

     while (reader.HasRows) 
     { 
      Console.WriteLine("\t{0}\t{1}", reader.GetName(0), 
       reader.GetName(1)); 

      while (reader.Read()) 
      { 
       Console.WriteLine("\t{0}\t{1}", reader.GetInt32(0), 
        reader.GetString(1)); 
      } 
      reader.NextResult(); 
     } 
    } 
} 

，用于从多个数据集的数据的关键是使用数据读取器样本
