Question 20

Explanation

What are Strings?

Strings are the data type corresponding to text. It is difficult to imagine an automation scenario that doesn’t involve the use of strings.

Anytime a text needs to be captured, processed, sent between applications, or displayed, string comes in handy (unless the data is structured - like a table).

Business scenarios uses of dictionaries

• Getting the status of an operation

• Extracting the relevant piece from a larger text portion

• Displaying information to the human user

String Methods

String manipulation is done by using String Methods borrowed from VB.Net. Below are some of the most common methods used in RPA:

Concat

Concatenates the string representations of two specified objects

Expression: String.Concat (VarName1, VarName2)

Contains

Checks whether a specified substring occurs within a string. Returns true or false

Expression: VarName.Contains (“text”)

Format

Converts the value of objects to strings (and inserts them into another text)

Expression: String.Format(“{0} is {1}”, VarName1, VarName2)

IndexOf

Returns the zero-based index of the first occurrence of a character in a String

Expression: VarName1.IndexOf(“a”)

Join

Concatenates the elements in a collection and displays them as String

Expression: String.Join(“|”, CollVarName1)

Replace

Replaces all the occurrences of a substring in a string

Expression: VarName.Replace (“original”, “replaced”)

Split

Splits a string into substrings using a given separator

Expression: VarName.Split(“|“c)(index)

Substring

Extracts a substring from a string using the starting index and the length

Expression: VarName1.Substring(startIndex, length)
