C# 使用Moq对请求中的文件进行计数

表单的
SetupGet
有效，但
计数无效。如何解决
Count
返回预期值的问题

var httpContextMock = new Mock<HttpContextBase>();
var request = new Mock<HttpRequestBase>();

httpContextMock.SetupGet(x => x.Request).Returns(request.Object);            
httpContextMock.SetupGet(x => x.Request.Form).Returns(form);
httpContextMock.SetupGet(x => x.Request.Files.Count).Returns(2);

var httpContextMock=new Mock（）；
var request=newmock（）；
httpContextMock.SetupGet（x=>x.Request）.Returns（Request.Object）；
httpContextMock.SetupGet（x=>x.Request.Form）.Returns（Form）；
httpContextMock.SetupGet（x=>x.Request.Files.Count）；
它不起作用，因为您设置了错误的模拟。在请求模拟上应用设置

var httpContextMock = new Mock<HttpContextBase>();

var requestMock = new Mock<HttpRequestBase>();
requestMock.Setup(_ => _.Form).Returns(form);
requestMock.Setup(_ => _.Files.Count).Returns(2);

httpContextMock.Setup(_ => _.Request).Returns(requestMock.Object);

它成功了。
我做了一个快速测试，如果您通过模拟上下文访问请求，它就会成功

    [Test()]
    public void Test()
    {
        var httpContextMock = new Mock<HttpContextBase>();
        var request = new Mock<HttpRequestBase>();

        httpContextMock.SetupGet(x => x.Request).Returns(request.Object);
        httpContextMock.SetupGet(x => x.Request.Files.Count).Returns(2);

        var count = httpContextMock.Object.Request.Files.Count;
        Assert.AreEqual(2, count);
    }

[Test（）]
公开无效测试（）
{
var httpContextMock=new Mock（）；
var request=newmock（）；
httpContextMock.SetupGet（x=>x.Request）.Returns（Request.Object）；
httpContextMock.SetupGet（x=>x.Request.Files.Count）；
var count=httpContextMock.Object.Request.Files.count；
断言。等于（2，计数）；
}

但是，正如Nkosi所建议的，您可能想要设置文件。请依靠requestMock本身。
它不起作用，因为您设置了错误的mock
    [Test()]
    public void Test()
    {
        var httpContextMock = new Mock<HttpContextBase>();
        var request = new Mock<HttpRequestBase>();

        httpContextMock.SetupGet(x => x.Request).Returns(request.Object);
        httpContextMock.SetupGet(x => x.Request.Files.Count).Returns(2);

        var count = httpContextMock.Object.Request.Files.Count;
        Assert.AreEqual(2, count);
    }
