FromBody how to binding string parameter

FromBody how to binding string parameter

In ASP.NET Web API, you can use the [FromBody] attribute to bind a string parameter in a POST or PUT request. Here's an example of how to bind a string parameter using [FromBody]:

public IHttpActionResult MyAction([FromBody] string myString) { // ... }

In this example, we have a method called MyAction that takes a single parameter called myString with the [FromBody] attribute applied. This indicates that the value for myString should be read from the request body.

When a request is made to the API endpoint that corresponds to MyAction, the content of the request body is read and converted to a string, which is then passed to the myString parameter.

Note that when binding a string parameter using [FromBody], the request body must be formatted as plain text, not JSON or XML. If the request body is formatted as JSON or XML, you should define a model class that corresponds to the structure of the request body and use [FromBody] to bind the model object instead.

By using [FromBody] to bind a string parameter in ASP.NET Web API, you can easily read and manipulate the contents of the request body in your API controller methods.
