如何从SqlDataReader读取多个结果集？

我有一个SP，我试图返回2个结果集，在我的.cs文件中我尝试这样的事情：

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 }; } 

但是我得到了：

错误：IndexOutOfRange {“EntityName”}

在这里，您有一个关于如何使用数据读取器处理多个结果集的示例

 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(); do { 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)); } } while (reader.NextResult()); } } 

从多个数据集中检索数据的关键是使用reader.NextResult
