winform httplicent调用API

绑定datagriview

   Uri uri = new Uri("http://localhost:49423");//地址
            HttpClient clien = new HttpClient();
            clien.BaseAddress = uri;
            clien.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


            HttpResponseMessage message = null;
            if(string.IsNullOrWhiteSpace(name))
            message= clien.GetAsync("api/show/Get").Result;
            else
                message = clien.GetAsync("api/show/Getcha?id="+name).Result;
            if (message.IsSuccessStatusCode)
            {
                var data = message.Content.ReadAsStringAsync().Result;

                var data2 = JsonConvert.DeserializeObject<DataTable>(data);


                dataGridView1.AutoGenerateColumns = false;
                dataGridView1.AllowUserToAddRows = false;
                dataGridView1.DataSource = data2;

修改

   /// <summary>
        /// 修改
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button2_Click(object sender, EventArgs e)
        {

            update up = new update();
            up.names.Text = dataGridView1.CurrentRow.Cells[1].Value.ToString();
             up.id.Text = dataGridView1.CurrentRow.Cells[0].Value.ToString();
            up.zhiwu.Text = dataGridView1.CurrentRow.Cells[2].Value.ToString();
            up.bili.Text = dataGridView1.CurrentRow.Cells[3].Value.ToString();
            up.phone.Text = dataGridView1.CurrentRow.Cells[4].Value.ToString();
            up.dizhi.Text = dataGridView1.CurrentRow.Cells[5].Value.ToString();
            up.beizhu.Text = dataGridView1.CurrentRow.Cells[6].Value.ToString();

            up.ShowDialog();//showdialog修改之后还能执行下面的代码
            bind("");
        }

保存修改

        {
            yuan mm = new yuan()
            {
                Beizhu = beizhu.Text,
                Bili = Convert.ToDecimal(bili.Text),
                Dizhi = dizhi.Text,
                Names = names.Text,
                Phone = phone.Text,
                Zhiwu = zhiwu.Text,
                id= Convert.ToInt32( id.Text)
            
            };
            Uri uri = new Uri("http://localhost:49423");//地址
            HttpClient clien = new HttpClient();
            clien.BaseAddress = uri;
            clien.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            HttpContent cotent = new StringContent(JsonConvert.SerializeObject(mm));

            cotent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

            HttpResponseMessage message = clien.PutAsync("api/show/update", cotent).Result;

            if (message.IsSuccessStatusCode)
            {
                var data = message.Content.ReadAsStringAsync().Result;

                if (Convert.ToInt32(data) > 0)
                {
                    MessageBox.Show("修改成功");
                    this.Close();
                }
