UiPath UiADAv1: How to Correctly Assign Data Table Rows to Dictionary in UiPath?

Learn the proper way to assign data table rows containing user IDs and usernames to a Dictionary<string, string> variable using a For Each Row activity in UiPath. Get the steps to map the user ID to the dictionary key and username to the value.

Question

A developer has created a data table. “dt_Users”, as shown in the following exhibit:

After scraping the data from a web application the developer wants to assign each row in the “dt_Users” variable to a Dictionary<string, string> variable, “DictUsers”. In addition, the developer wants to assign the user IDs to the keys and the usernames to the values inside a For Each Row activity.

How should the Assign activity be configured?

A. DictUsers(CurrentRow(1).ToString) = CurrentRow(0).ToString
B. CurrentRow(1).ToString = DictUsers(CurrentRow(0).ToString)
C. DictUsers(CurrentRow(0)) = DictUsers(CurrentRow(1).ToString)
D. DictUsers(CunrentRow(1).ToString) = DictUsers(CurrentRow(0).ToString)

Answer

The correct option to assign each row in the “dt_Users” data table to the “DictUsers” Dictionary<string, string> variable is:

A. DictUsers(CurrentRow(1).ToString) = CurrentRow(0).ToString

Explanation

Here’s why:

• The dictionary keys should be the user IDs, which are in the 2nd column (index 1) of the data table.
• The dictionary values should be the usernames, located in the 1st column (index 0).
• CurrentRow(1) accesses the user ID in the current row being processed by the For Each Row activity. This needs to be converted to a string using ToString() to match the Dictionary’s defined key type of string.
• Similarly, CurrentRow(0) retrieves the username string in the current row.
• The other options have the key/value assignments reversed, use incorrect indexing, or assign to the wrong variables.

So in summary, inside the For Each Row, each iteration will assign the current row’s user ID (converted to string) as a key in DictUsers, and the corresponding username as the value. This will populate your DictUsers dictionary as intended.
