c#winform通过http请求上载文件异常：未找到多部分边界
我正试图使用httpwebrequest将一个文件上传到apache服务器，这是我的c代码c#winform通过http请求上载文件异常：未找到多部分边界,c#,apache,http-post,C#,Apache,Http Post,我正试图使用httpwebrequest将一个文件上传到apache服务器，这是我的c代码 您可以使用2个额外的--创建endBoundary，但从不将其附加到请求的末尾。如果这不能解决问题&您看不到有什么问题，请将您的请求与运行Fiddler的浏览器发出的工作请求进行比较，并查找差异。同时更改为f_request.ContentType=“multipart/form data；boundary=“+strBoundary，当前标头中没有边界=标记。我将该endBoundary添加到requs
您可以使用2个额外的
