我试图完成这项工作并进行了许多google/stackoverflow搜索而根本没有运气.

我有一个简单的模型:

public class MovieModel
{
    public string Id { get; set; }

    [Required]
    [StringLength(100)]
    public string Name { get; set; }
}

控制器中的方法:

// POST: api/Movies
public IHttpActionResult Post([FromBody]MovieModel movieModel)
{
    if (ModelState.IsValid)
    {
        //Code
    }
}

一个测试方法(是一个集成测试,但在单元测试中会发生同样的情况):

[TestMethod]
public void MoviesController_Post_Without_Name()
{
    // Arrange
    var model = new MovieModel();
    model.Name = "";

    // Act
    var result = controller.Post(model);

    // Assert
    Assert.IsInstanceOfType(result, typeof(InvalidModelStateResult));
    Assert.AreEqual(6, controller.Get().Count());
}

尽管模型显然无效,但它总是将IsValid属性评估为true.

到目前为止,我尝试了许多方法但没有成

我很难完成这项工作。我的图像集由小图像 (58x65) 组成。

我正在使用带有以下参数的 ORB：

# Initiate ORB detector
# default: ORB(int nfeatures=500, float scaleFactor=1.2f, int nlevels=8, int edgeThreshold=31, int firstLevel=0, int WTA_K=2, int scoreType=ORB::HARRIS_SCORE, int patchSize=31)
orb = cv2.ORB_create(
  nfeatures = 500,                    # The maximum number of features to retain.
  scaleFactor = 1.2,                  # Pyramid decimation ratio, greater than 1
  nlevels = 8,                        # The number of pyramid levels.
  edgeThreshold = 7,                  # This is size of the border where the features are not detected. It should roughly match …
