使用Moq模拟AspnetMvc中的Request.Form

1、比如Request.Form["ddlType"]为control中需要模拟的内容

2、在单元测试中调用的代码（使用的是VS2010自带的单元测试框架）         

       var request = new Mock<HttpRequestBase>();
            //request.Setup(r => r.HttpMethod).Returns("Post"); //这里Post和Get都行，可不添加此行代码
            //request.Setup(r => r.PathInfo).Returns(string.Empty);//可不添加此行代码
 
            //需要模拟的Request.Form键值对
            var formvalues = new NameValueCollection { { "ddlType1", model.ddlType1}, { "ddlType2", model.ddlType2 } };
 
            var mockHttpContext = new Mock<HttpContextBase>();
            mockHttpContext.Setup(c => c.Request).Returns(request.Object);
            mockHttpContext.Setup(c => c.Request.Form).Returns(formvalues);

            Mock<EnterpriseRepository> mockEnterprise = new Mock<EnterpriseRepository>();
            EnterpriseController controller = new EnterpriseController(mockEnterprise.Object); //Control
            var context = new ControllerContext(mockHttpContext.Object, new RouteData(), controller);

            controller.ControllerContext = context;  //设置control的context熟悉
           var result = controller.Create(model); //调用action方法
