What are the differences between model binding attributes in ASP.NET?

What are the differences between model binding attributes in ASP.NET?

In ASP.NET, model binding attributes like [FromBody], [FromQuery], and [FromRoute] specify how data is bound to action parameters. [FromBody] binds data from the request body, [FromQuery] binds from the query string, and [FromRoute] binds from the route data.

Can you give examples of when to use each attribute?

Sure! Use [FromBody] when sending complex objects in JSON format, [FromQuery] for simple data types in the URL, and [FromRoute] when you want to extract values directly from the URL path.

Are there any performance implications of using these attributes?

Yes, using [FromBody] can be less efficient for simple data types since it requires deserialization. In contrast, [FromQuery] and [FromRoute] are generally faster for primitive types.

What happens if I don't specify any binding attribute?

If no binding attribute is specified, ASP.NET will use default model binding, which may lead to unexpected results, especially if there are multiple sources of data.
