The purpose of the Invoke Code activity in UiPath is to invoke VB.NET or C# code, optionally passing it a list of input arguments. The Invoke Code activity allows the developer to write and execute custom code in VB.NET or C# within a UiPath workflow. The Invoke Code activity has a Code property, where the developer can enter the code to be executed. The Invoke Code activity also has an Arguments property, where the developer can specify the input and output arguments for the code. The Invoke Code activity can be useful for performing complex calculations, manipulating data, or integrating with external libraries or applications that are not supported by the existing UiPath activities. References: [Invoke Code]
