I have an ASP.NET Core 5 Web API. How can I return the results from all my controllers in a Result object, regardless of the return type of controller?
Something like this:
Result: {
"isSuccess": {{True or False}},
"value": {{Result Value Object}},
"error": {{Error Object}},
"totalCount": {{number of results, in case the result is list}}
}
You should be able to implement what you're looking for like this:
public class ResultActionResult<T> : ActionResult
{
public ResultActionResult(T value)
{
Value = value;
IsSuccess = true;
}
public ResultActionResult(Error error)
{
Error = error;
IsSuccess = false;
}
public T Value { get; }
public Error Error { get; }
public bool IsSuccess { get; }
public int? TotalCount { get; set; }
public override async Task ExecuteResultAsync(ActionContext context)
{
var objectResult = new ObjectResult(this)
{
StatusCode = IsSuccess ? 200 : 400
};
await objectResult.ExecuteResultAsync(context);
}
}
This will give you two constructors: one for successful results and the other one for error results. The four properties: Value will hold the result value object, Error will hold the error object, IsSuccess will be your boolean telling you whether the result is a success or an error, and TotalCount will holds the total number of results in case the result is a list. The class also overrides the ExecuteResultAsync method to return an ObjectResult with a status code of 200 for success and 400 for error.
To use it simply return an instance from your controller action. Hope that's what you're looking for.
