c#-httpclient-如何在多部分中将Content-Disposition设置为“ application / json;”

我正在尝试使用System.Net.Http.Httpclient在C#和wp8中编写多篇文章.

这是我的代码的片段：

varclient = new HttpClient();

client.DefaultRequestHeaders.TryAddWithoutValidation(    
"Content-Type", "application/json");

content = new MultipartFormDataContent();
content.Add(new StringContent(requestObj, Encoding.UTF8, "application/json"), "request");

但是使用Fiddler,我注意到我发送的是：

内容处置：表单数据；名称=请求

内容类型：文本/纯文本；字符集= utf-8

而我需要发送此消息(取自通话正常的android设备)：

内容处置：application / json; name =“ request”

内容类型：文本/纯文本；字符集= UTF-8

>如何达到预期效果？

解决方法:

关于什么：

使用TryAddWithoutValidation在HttpContent上设置标头

并将MultipartFormDataContent更改为MultipartContent对象：

var content = new MultipartContent();

var contentData = new StringContent(requestObj, Encoding.UTF8, "application/json");
contentData.Headers.TryAddWithoutValidation("Content-Disposition", "application/json name=request");
content.Add(contentData);

这导致这些标题
