Types of Variables
A text or string variable is a type of variable that can store only strings. These types of variables can be used to store any information such as employee names, usernames or any other string.
To exemplify how you can work with text variables, we are going to create a project that asks for the user’s name, stores it and displays only the first letter of his name in the Output panel.
The true or false variable, also known as boolean, is a type of variable that only has two possible values, true or false. These variables enable you to make decisions, and thus have a better control over your flow.
To exemplify how you can work with true or false variables, we are going to create an automation that asks the user for his name and gender, and displays the results in another window.
Number variables are also known as integer or Int32, and are used to store numeric information. They can be used to perform equations or comparisons, pass important data, and many others.
To exemplify how you can work with number variables, we are going to create an automation that asks the user for the year in which he or she was born and displays the age in a window.
The final project should look as in the following screenshot.
11. Press F5. The automation is executed. Note that the Message Box displays your age, as expected.
The array variable is a type of variable which enables you to store multiple values of the same type.
UiPath Studio supports as many types of arrays as it does types of variables. This means that you can create an array of numbers, one of strings, one of boolean values and so on.
.txt
file.
System.DateTime
. For more information, see Browsing for .Net Variable Types.
For example, they can be used to append dates to invoices or any other documents you may be working with and are time-sensitive.
To exemplify how you can work with a date and time variable, we are going to build an automation that gets the current date and time, subtracts a specific amount of time and writes the result to a Microsoft Excel spreadsheet.
DataTable variables represent a type of variable that can store big pieces of information, and act as a database or a simple spreadsheet with rows and columns. They can be found in the Browse and Select a .Net Type window, under the System.Data namespace (System.Data.DataTable). For more information, see Browsing for .Net Variable Types.
These variables can be useful to migrate specific data from a database to another, extract information from a website and store it locally in a spreadsheet and many others.
To exemplify how you can use DataTable variables, we are going to create an automation that reads only two out of multiple columns from an Excel spreadsheet, and then transfers them to another spreadsheet that already contains other information.
The initial file is a database of people, transactions, dates, and products. In this example, we are going to extract their names and order dates and append them to an Excel spreadsheet that already contains similar information.
