我正在使用网络客户端下载它

var json= client.DownloadString(uri);

结果和预期的差不多，但是它改变了一些字符串格式，比如响应的属性有一些使用特殊字符的值

eventDescription: "TUM is Canada’s first and only social food market designed to give budding food entrepreneurs, chefs and home cooks a platform to test new food ideas to an eager market. Since September 2011, each TUM event has featured new cooks & chefs wanting to exhibit their food plus various local craft beer, wine & cocktails.",

它改变它喜欢

 eventDescription: "TUM is Canada’s first and only social food market designed to"

我想要同样的回应。请问有什么建议吗？

你必须在调用DownloadString()之前设置文本编码。

client.Encoding = Encoding.UTF8;

要确定使用哪种编码，请检查服务的 Content-Type 响应标头。

Content-Type:application/json;charset=UTF-8
