如何使用SqlDataReader从没有列名的数据读取

Question

I have Visual Studio 2013 Ultimate and creating application of WPF.

I have to read the data from a SQL Server stored procedure by using SqlDataReader .

1. Sometimes, if data exists, I can read data using sdr(sqldatareader).Read()

2. But in the case when no data exists, I just select 'false' in stored procedure but I don't know how to read that string with having no column name by SqlDataReader .

Answer 1

你可以这样做。

reader.GetString(0); //0 stands for "the 0'th column"
