Is there way to rewrite:
var tbl = ds.TABLES;
var q = from c in tbl
select c.TABLE_TYPE;
string s = "";
foreach (var item in q.Distinct())
{
s += "[" + item + "]";
}
MessageBox.Show(s);
So that the Distinct() call is in the LINQ query?
The
Distinctextension method in LINQ does not have a query syntax equivalent.See https://learn.microsoft.com/en-us/archive/blogs/charlie/linq-farm-using-distinct-and-avoiding-lambdas for additional information as to why.
