You can use a linq lambda for this.

column[] columns = getColumninfo();
columns.ToDictionary(x => x.name, y => y);

By adding StringComparer.OrdinalIgnoreCase you can ensure that the column name lookup is case insensitive.

columns.ToDictionary(x => x.name, y => y, StringComparer.OrdinalIgnoreCase);
