Question

我知道这是一个经常被问到的问题，但我找不到答案。我正在尝试一个Microsoft Emotion API（我在这里使用通用密钥来提问），并且它一直给我错误，“WindowsFormsApp2是一个命名空间但是用作一个类型”即使我更改命名空间。我将命名空间更改为更合适的标题，但我仍然收到WindowsFormsApp2被不恰当地用作类型的构建错误，尽管它在代码中没有任何地方。我不知道我在哪里使用它，它正在创建这个问题。

这是我的代码：

using System.Windows.Forms;
using System.IO;
using System.Net.Http.Headers;
using System.Net.Http;

namespace WindowsFormsApp2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            {
                textBox1.Text = ("Enter the path to a JPEG image file:");
                openFileDialog1.ShowDialog();
                string imageFilePath = openFileDialog1.FileName;

                MakeRequest(imageFilePath);

                textBox1.Text = ("\n\n\nWait for the result below, then hit ENTER to exit...\n\n\n");
            }


            byte[] GetImageAsByteArray(string imageFilePath)
            {
                FileStream fileStream = new FileStream(imageFilePath, FileMode.Open, FileAccess.Read);
                BinaryReader binaryReader = new BinaryReader(fileStream);
                return binaryReader.ReadBytes((int)fileStream.Length);
            }

            async void MakeRequest(string imageFilePath)
            {
                var client = new HttpClient();

                // Request headers - replace this example key with your valid key.
                client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "13hc77781f7e4b19b5fcdd72a8df7156");

                // NOTE: You must use the same region in your REST call as you used to obtain your subscription keys.
                //   For example, if you obtained your subscription keys from westcentralus, replace "westus" in the 
                //   URI below with "westcentralus".
                string uri = "https://westus.api.cognitive.microsoft.com/emotion/v1.0/recognize?";
                HttpResponseMessage response;
                string responseContent;

                // Request body. Try this sample with a locally stored JPEG image.
                byte[] byteData = GetImageAsByteArray(imageFilePath);

                using (var content = new ByteArrayContent(byteData))
                {
                    // This example uses content type "application/octet-stream".
                    // The other content types you can use are "application/json" and "multipart/form-data".
                    content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
                    response = await client.PostAsync(uri, content);
                    responseContent = response.Content.ReadAsStringAsync().Result;
                }

                //A peak at the JSON response.
                textBox1.Text = (responseContent);
            }



        }

    }
}

我不喜欢你// test.py from tag36h11_detector import detect import numpy as np a = np.array([1,2,3], dtype=np.uint8) detect(4, 5, a)之后的分号。

InitializeComponent()

Answer 2

我发现了问题，实际上并不在提供的代码中。 IDE认为问题出在表单中，但自动代码生成器使用命名空间而不是建立表单。错误形式认为问题出现在表单的第19行，但它实际上是在program.cs文件的开头。我希望这不会经常发生。

“FormsApp是一个命名空间，但使用的类似”
