問題場(chǎng)景見下面的示例代碼：public class ErrorsController : Controller{ public IActionResult StatusCodePage(int? statusCode) { bool viewExists = false; //TODO:檢查對(duì)應(yīng)于statusCode的視圖文件是否存在
return viewExists ? View(statusCode.Value) : View("Default");
}
}
請(qǐng)問如何實(shí)現(xiàn)？

通過 ICompositeViewEngine.FindView() 解決了
public class ErrorsController : Controller{ public IActionResult StatusCodePage(int? statusCode, [FromServices]ICompositeViewEngine compositeViewEngine) { bool viewExists = statusCode.HasValue &&
compositeViewEngine.FindView(ControllerContext, statusCode.Value.ToString(), true).Success;
return viewExists ? View(statusCode.Value.ToString()) : View("Default");
}
