Hi,

I am writing a linq qyery to get the output, but i want some alias names for the columns. my query is like this

C#

var q = from a in Number
        join b in Dupnum on a.ID equals b.ID
                           select new
                           {
                                a.Number ,
                                a.LineNumber,
                               a.Item,
                               a.Des,
                               a.SerialNumber
                           };

I am writing like this for alias name

C#

["Number#"] = a.Number ,
[Lime Number#] =a.LineNumber

But it was throwing me the error like" Invalid anonymous type member declare, anonymous type must be declare"

I had the same problem and added a dot in-front of the alias. So in your code case it would be

.["Number"] = a.Number ,
.[Lime Number] =a.LineNumber

All the best,
Tony

Solution 3 is wrong, can't provide an alias with spaces by any approach in linq.

Solution 12

You can also use the let operator for your query like:

var q = from a in studentList
let Number = a.Number
let LimeNumber = a.LineNumber
select new { Number, LimeNumber	};

You should be able to simply define an alias without any extra characters as long as the names of the aliases conform to C# naming rules. For example, try the following:

C#

var q = from a in Number
        join b in Dupnum on a.ID equals b.ID
                           select new
                           {
                               f1 = a.Number ,
                               f2 = a.LineNumber,
                               f3 = a.Item,
                               f4 = a.Des,
                               f5 = a.SerialNumber
                           };
