.NET 7 is a new version of .NET that adds an interface called IParsable. This interface helps developers parse strings in their code more easily.

The IParsable interface consists of two methods: Parse and TryParse.

Documentation:https://learn.microsoft.com/zh-cn/dotnet/api/system.iparsable-1

The Parse method is used to resolve a string to a value of a specified type. If resolution fails, an exception is thrown.

The TryParse method is used to resolve a string to a value of a specified type. It does not throw an exception, but returns a boolean value indicating whether the resolution was successful.

For example, the following code demonstrates how to parse a string into an integer using the Parse method:

If we want to use the TryParse method to parse strings, we can use the following code:

In this code, the success variable will contain a boolean value indicating whether the resolution was successful or not. If the resolution is successful, the value variable will contain the parsed integer.

We create a new User class that contains the Name, Age attributes, we wantPass in a comma-separated string to return the User object, as shown in the figure below:



The full code is as follows:


In conclusion, IParsable interfaces can make it easier to parse strings and can make code more concise and readable. If you are using .NET 7 to develop applications, then you should consider using this interface.
