Public Author ConvertAuthorDtoToAuthor(AuthorDto authorDto) public AuthorDto ConvertAuthorToAuthorDto(Author author) The following two methods show how you can convert an Author instance to an AuthorDto instance and convert and AuthorDto instance to an Author instance. Convert model to DTO and vice versa in C# A data transfer object is a container of data used to pass data between the layers of an application. The AuthorDto class represents the data transfer object of the Author class. In the preceding code snippet, the Author class is the model, i.e., it represents the Author entity. Let’s now understand how we can use implicit and explicit conversions in user-defined data types, i.e., classes.Ĭonsider the following two classes. The above code will compile successfully without any errors. You can fix the non-compilable code snippet by specifying an explicit type cast of double to int as shown in the code snippet below. This type of type casting is known as explicit type casting because you must write explicit code to perform the type casting. The error indicates that the runtime will not convert a double to an int without explicit type casting. The compiler won’t let you assign a double to an integer variable in C#. Here’s the error you’ll observe In Visual Studio on compilation of the above code snippet.įigure 1. However, note that the following code will not compile. Here is an example that illustrates an implicit conversion: int x = 100 You don’t need to cast to any specific type. What are implicit and explicit type conversions?Īn implicit type conversion is one that is done by the runtime automatically. We’ll use this project to work with type conversions in the subsequent sections of this article. NET Core console application project in Visual Studio 2022. In the “Additional information” window shown next, choose “.NET 7.0 (Standard Term Support)” as the framework version you want to use.įollowing these steps will create a new.In the “Configure your new project” window shown next, specify the name and location for the new project.In the “Create new project” window, select “Console App (.NET Core)” from the list of templates displayed.
