它给我文件不在这一行：

httpUrlConn.getInputStream());
答案 0 :(得分：0)
不要使用客户端来读取文件，这似乎是你想要做的。
就我个人而言，我的上传方法签名有以下几点：
//Server
public void UploadFile(bytes[] file, string name)
{
//Store the BLOB object
}
//Client
public void SendFile()
{
var bytes = File.ReadAllBytes("Filename");
UploadFile(bytes, new FileInfo("Filename").Name);
}
请注意，您已经在C#中完全标记了您的问题，这就是我给出的答案，如果您需要转换它，请使用online convertor。
