Append columns from one data table to another data table

DIVIJ Published at Dev

I have multiple data tables(upto 28) in C# and I want to append all their columns in one data table(with data). Example: datatables are: DT1,DT2,DT3 and so on Number of Columns in these respective data tables: N1,N2,N3 and so on Output: One data table DT with total columns N1+N2+N3+... and all the data from the above data tables. Thanks. Edit: My tables have clustered primary keys.

var all = new DataTable();

all.Merge(DT1);
all.Merge(DT2);
all.Merge(DT2);

... better to use in a loop.
