Hey @naveen.s
Use below mentioned LinQ:
isItemFound = dt_Input.AsEnumerable().Any(Function(row) row("YourColumnName").ToString.Trim.Equals(QueueItem.SpecificContent("YourKey").ToString))
Note: isItemFound is a Boolean Variable.
If the value Is available then boolean variable will be True else False.
Best regards,
