Question

我在尝试从Windows窗体应用程序向WebApi发送带有7.8等十进制值的WebClient请求时遇到问题。当我尝试在WebApi的Controller上访问此值时，此值为Nothing。

这是我的模特：

Public Class ProductModel
    Public Property Name As String
    Public Property Quantity As Decimal?
    Public Property Price As Decimal?
End Class

这是我在Windows窗体应用程序上的请求函数：

Public Function SendProduct() As String    
        Using client As New WebClient
            client.Headers.Clear()
            client.Headers(HttpRequestHeader.ContentType) = "application/x-www-form-urlencoded"
            client.Encoding = Text.Encoding.UTF8

            Dim params As New Specialized.NameValueCollection

            params.Add("Name", "Product 1")
            params.Add("Quantity", CDec(7.0))
            params.Add("Price", CDec(7.8))

            Dim responseBytes As Byte() = client.UploadValues("http://localhost:50305/mycontroller/sendproduct", "POST", params)
            Dim response As String = (New Text.UTF8Encoding).GetString(responseBytes)

            Return response
        End Using
End Function

以下是我对Controller的行动：

<HttpPost>
Public Function SendProduct(<FromBody> model As ProductModel) As IHttpActionResult   
    'At this point my model values are:
    'model.Name = "Product 1"
    'model.Quantity = 7
    'model.Price = Nothing (Here is the problem)
End Function

请注意，数量也是小数，并且发送正确

我弄清楚问题是什么。我在CDec(7.8).ToString().Replace(",", ".")上添加的值在运行时被解析为字符串，因此当添加十进制值时，值将更改为＆＃34; 7,8＆＃34;逗号是问题所在。对于测试我只做toggleFullscreen()并且它有效。所以现在我正在改变另一种方式来正确发送数据。

无论如何，不管怎么说！

通过WebClient发送十进制值，在Controller上获取Nothing
