10.1) If Else

In UiPath, the If statement is exactly how you’d expect it to be:

 

• The condition that is verified (with 2 potential outcomes – true or false
• The set of actions to be executed when the condition is true (the Then branch)
• The set of actions to be executed when the condition is false (the Else branch)

What is different is that, based on the chosen type of automation project, there are 2 corresponding activities that fulfill the If statement role:

• The If Statement in sequences
• The Flow Decision in flowcharts
• Using VB .Net operator

Moreover, the If decision can be used as an operator inside activities.   

What are some business scenarios in which I will use the If statement?

Whenever there are two courses of action that are not arbitrary, an If statement will most likely be used:

• Checking the status of a payment (done/not done) and performing a set of operations in each case
• Making sure that the outcome of the previous operation in the sequence is successful
• Checking the balance of an account to ensure that there is enough money to pay an invoice
• Checking if something has happened in a system, like if an element or an image exists and performing an action based on that. 

Example: Business purpose we need to check if the year is leap year. An year is leap year if it meets the below conditions, if:

• The year is evenly divisible by 4
• The year can be evenly divided  by 100, it is not a leap year, unless the year  is also  evenly  divisible by 400

1) Using If Else Activity

              

2) Using Flow Decision

                        

Add the same VB condition in Flow Decision -> condition option in properties panel

3) Using VB.net

• Create Sequence, Add INput dialog to enter year
• Create 2 variables year and message
• Add assign activity and in the value add the VB.net expression 

    Robot will look like

                                

             

We can have nested if in if statements.
