使用 Response.StatusCode 设置和获取方法。

本地异常处理：对于本地操作异常处理，请将以下内容放入调用代码中。

Local Exception handling: For local action exception handling, put the following inside the calling code.

var responseCode = Response.StatusCode;
try
{
    // Exception was called
}
catch (BusinessLayerException1)
{
    responseCode = 201
}
catch (BusinessLayerException2)
{
    responseCode = 202
}
Response.StatusCode = responseCode;

关于跨控制器行为：您应遵循以下步骤。

1. 创建抽象BaseController


2. 使您当前的Controller继承自BaseController。


3. 在BaseController中添加以下逻辑。

BaseController.cs

public abstract class BaseController : Controller
{
    protected override void OnException(ExceptionContext filterContext)
    {
        var responseCode = Response.StatusCode;
        var exception = filterContext.Exception;
        switch (exception.GetType().ToString())
        {
            case "ArgumentNullException":
                responseCode = 601;
                break;

            case "InvalidCastException":
                responseCode = 602;
                break;
        }
        Response.StatusCode = responseCode;
        base.OnException(filterContext);
    }
}

注意：
您还可以添加已处理的异常并将其重定向到其他 Controller / Action

filterContext.ExceptionHandled = true;
filterContext.Result = this.RedirectToAction("Index", "Error");
