Hello @shilpa_p ,

You can use this in the if condition inside for each row to check if value is present in your dictionary:
Dict.Keys.Contains( CurrentRow(“Name”).ToString)

If it contains, you can add the row to your list/array using “Add To Collection” activity.

Thanks,

Hi @shilpa_p ,

Let’s say we have the following the variables :

DT as a Datatable variable, item as a String, dictVar as a Dictionary, dataRowList as List of DataRow.

  1. Checking the Item is Present in the Dictionary. Assuming that we are Checking the name, which is the Key in Dictionary we can do the following by Specifying the condition below in an If Activity:
dictVar.Keys.Any(Function(x)x.ToString.Trim.Equals(item.ToString.Trim))

if the Check is for the Values, we can use the below Expression :

dictVar.Values.Any(Function(x)x.ToString.Trim.Equals(item.ToString.Trim))
  1. In the Then Part, we can get the Matching DataRow from Datatable using an Assign Activity in the below way :
arrayRow = DT.AsEnumerable.Where(Function(x)x("Name").ToString.Trim.Equals(item.ToString.Trim)).ToArray

where arrayRow is a variable of Type Array of DataRow

  1. Next, we can Check if arrayRow has any values using an If Activity with Condition in the below way :
arrayRow.Any
  1. In the Then Part of If, we can Add the DataRow to the List of DataRows using an Invoke Method Activity.

Using a For Each to Loop through the Collection of Matched DataRows, add to the List of DataRows, Like Below :

@shilpa_p , We would also need to make sure the dataRowList is initialised, Hence, We do the following at the beginning, or as a Default value for the variable :

dataRowList = new List(Of DataRow)

sure. I will do that
