UiPath UiPath-ADAv1 Dumps Questions Answers

The String.Join method takes two parameters: a separator and an array of strings. It returns a new string that concatenates the elements of the array using the separator. The correct syntax is String.Join(separator, array). Therefore, option B is the correct answer.

Comprehensive and Detailed In-Depth Explanation:

The given expression uses the Split function, which divides a string into an array based on a delimiter.

Step-by-Step Execution Guide: Understanding Split() Behavior

Given Code in UiPath:

Dim StrValue As String = "2023"

Dim SplitResult() As String = StrValue.Split("2"c) ' Split by character "2"

For Each currentItem In SplitResult

Log Message: currentItem

"" (empty)

Before the first "2"

1

"0"

Between the two "2"s

2

"3"

After the last "2"

???? Final Output: 0 3 (each part printed separately).

Real-World Use Case: Extracting File Extensions

???? Scenario: A bot processes filenames and needs to extract extensions.

vb

CopyEdit

Dim FileName As String = "Report.PDF"

Dim Extension As String = FileName.Split("."c)(1)

???? Output: "PDF"

???? Split is powerful for handling structured text processing!

Why the other options are incorrect?

❌ A. 00 – The split function does not duplicate numbers.

❌ B. 20 23 – The space between 20 and 23 never exists after splitting.

❌ C. 2023 – The split function removes the delimiter (2), so 2023 is not possible.

The error "Object reference not set to an instance of an object" occurs because dtReports has not been initialized before use.

To fix this, the correct approach is to initialize the DataTable before adding rows, using:

dtReports = New System.Data.DataTable

Explanation of Each Option:

A (Assign dtReports = New System.Data.DataTable) ✅ (Correct Answer)

Initializes a new empty DataTable, which is required before adding rows.

Once initialized, dtReports can hold columns and rows.

B (Assign New System.Data.DataTable = dtReports) ❌ (Incorrect)

Incorrect syntax. New System.Data.DataTable must be assigned to a variable, not the other way around.

C (Assign dtReports = New System.Data.DataRow) ❌ (Incorrect)

DataRow represents a single row, not the entire DataTable.

We need to initialize the table first, not just a row.

D (Assign dtReports = New List(Of DataRow)) ❌ (Incorrect)

A List(Of DataRow) is not a DataTable. UiPath's Add Data Row activity only works with DataTable, not with lists.
