In this section we will talk about Identity and Access Management – IAM in short. I will show you an example of using AWS CDK to create IAM roles with C# and extending our current solution so that an IAM Role is ready with the correct permission to use. We will mainly focus on IAM […]

1 2 3 4 5 6 7 |
string hourString = "5"; int hour; if (int.TryParse(hourString, out hour)) { Console.WriteLine($"The hour is {hour}"); } |
The improvement that C#7 brings is you can now declare out variables in the argument list of a method call, rather than writing a separate declaration statement like below:
1 2 3 4 5 6 |
string hourString = "5"; if (int.TryParse(hourString, out int hour)) { Console.WriteLine($"The hour is {hour}"); } |
And it doesn’t end there […]
