How to read from a data with no column name using SqlDataReader

问题

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.

回答1:

You can do this.

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