UiPath UiRPA v1.0: Which expression used to return the first four characters from String variable called StrVar?

Question

Which expression should be used to return the first four characters from a String variable called StrVar?

A. StrVar.Substring(0, 4)
B. StrVar.Substring(1, 4)
C. StrVar.Substring(1, 5)
D. StrVar.Substring(4)

Answer

A. StrVar.Substring(0, 4)

Explanation

The correct answer is A. StrVar.Substring(0, 4).

The Substring() method of the String class in UiPath is used to extract a substring from a string. The method takes two arguments: the start index and the length of the substring. In this case, we want to extract the first four characters from the string, so we would use the following expression:

StrVar.Substring(0, 4)

The first argument, 0, specifies the start index of the substring. The second argument, 4, specifies the length of the substring. The method will return a new string that contains the specified substring.

The other options are not correct.

  • B. StrVar.Substring(1, 4) will return the characters from index 1 to index 4. This will not return the first four characters if the string is longer than 4 characters.
  • C. StrVar.Substring(1, 5) will return the characters from index 1 to index 5. This will return more than four characters if the string is longer than 5 characters.
  • D. StrVar.Substring(4) will return the characters from index 4 to the end of the string. This will not return the first four characters.
