有没有办法将IEnumerable参数传递给另一种方法 [英] Is there a way to pass an IEnumerable parameter to another method

问题描述

我正在尝试将IEnumerable模型参数从一种方法传递给另一种方法，但是当我调试代码时，即使方法签名相同，也不会传递该参数.

I am trying to pass a IEnumerable model parameter from one method to another however when I debug the code the parameter is not being passed even though the method signature is the same.

我尝试了有无前缀前缀

方法1:

[HttpPost]
    public ActionResult Create_Filter([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<CourseFilterViewModel> courseFilterVM)
    {


        return RedirectToAction("Course", "Filter", courseFilterVM);
    }

方法2:

public ActionResult Course([Bind(Prefix = "models")]IEnumerable<CourseFilterViewModel> courseFilterVM)
    {

        return View(courseFilterVM);
    }

我希望整个模型都可以通过，但是我得到的是空值.

I am expecting the entire model to be passed but instead I am getting a null value.

推荐答案

您可以简单地执行以下操作:

You can simply do as follows:

[HttpPost]
public ActionResult Create_Filter([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<CourseFilterViewModel> courseFilterVM)
{
    // Others stuffs  here

    return Course(courseFilterVM);
}
