Hi,

If you need single string, the following works.

String.Join(",",ExtractDataTable.AsEnumerable.Select(Function(r) r("Agent_Name").ToString))

If you need String array, the following will work.

ExtractDataTable.AsEnumerable.Select(Function(r) r("Agent_Name").ToString).ToArray()

The provided conversation offers a solution for converting a UiPath DataTable containing agent names and URLs into a single string format. Here’s a breakdown of the approaches and the winning solution:

Problem:

The user wants to convert a DataTable extracted using “Extract DataTable” activity to a single string where all agent names are comma-separated. They don’t need the URLs and want the names in one cell.

Solution:

The solution provided by Yoichi (MVP 2024) utilizes LINQ with the Select and Join methods:

1. ExtractDataTable.AsEnumerable: This converts the DataTable to an IEnumerable collection, allowing for LINQ operations.
2. Select(Function(r) r("Agent_Name").ToString): This part iterates through each row (r) in the collection and selects the value of the “Agent_Name” column. The ToString method ensures it’s converted to a string.
3. String.Join(",", ... ): Finally, the String.Join method combines all the extracted agent names into a single string separated by commas (“,”).

Alternative (String Array):

Yoichi also offers an alternative approach using ToArray if the user needs the names as a String array instead of a single string.

Key Points:

• This solution leverages LINQ for concise and efficient data manipulation.
• It assumes the DataTable has a column named “Agent_Name” containing the desired names.

Additional Considerations:

• If the DataTable structure is more complex or the column names differ, you might need to adjust the code accordingly.
• Error handling can be added to gracefully handle potential issues like missing columns or empty DataTables.

By applying this solution, the user can achieve the desired format of having all agent names from the DataTable combined into a single comma-separated string within their UiPath workflow.

Hi @Venky_Mama

Try as below:-

stringVar = String.Join(“,”, dataTable.AsEnumerable().Select(Function(row) row.Field(Of String)(“Column1”)).ToArray())

Use write cell in excel & pass stringVar.

Thanks
