The following activity illustrates on how we can use the get value activity to derive the value of a specific key from the dictionary. We will be using the continuity of the same example that we used in add to dictionary activity.
Example:
1. Drag and drop a get value activity from the dictionary tab below the add to dictionary activity.
2. Specify the name of the dictionary from which the value must be derived. Here it is DictNameAge.
3. Enter the key for which the value is required within double quotes. Here we will get the value for the name “John”.
4. Declare a variable in the Value box of Output segment. Let’s use Jvalue here.
5. Drag and drop a message box below the get value activity to view the details.
6. In the input string add the declared variable and .ToString to it as the message box accepts only string values. E.g., Jvalue.ToString
7. Execute the activity.
The bot executes the activity and derives the value for the key “John”.
