Using Procedural Activities

Using Procedural Activities

.NET Framework 4.6 and 4.5

The sample uses the Sequence, Assign, If, While, Switch, TryCatch, and WriteLine activities to implement a guessing game. The guessing game selects a random number and the player has to guess that number. When the player submits an incorrect guess, the workflow provides a hint whether to guess higher or lower. If the player guesses the number in less than 7 attempts, a special congratulations is displayed to the user.

Custom Activities in this Sample

ReadLine

Reads a line of text from the console. This activity derives from the NativeActivity class and creates a bookmark that is resumed by the console application when a line is read.

PromptInt

Prompts the user to type in a number and then reads it from a console window. The activity derives from Activity and uses the WriteLine and ReadLine activities.
