在WINFORMS中将整个文件读入字节数组
我想读取使用文件对话框打开的文件的内容，然后将其保存在字节数组中以将其传递给 Web 服务
Stream myStream;
OpenFileDialog saveFileDialog1 = new OpenFileDialog();
saveFileDialog1.Filter = "zip files (*.zip)|*.zip|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
NSITESERVICE.UploadSoapClient obj = new NSITESERVICE.UploadSoapClient();
byte[] filebytes = //what should i pass it over here...
obj.UploadFile("kamal", "p@ssword", filebytes);
// Code to write the stream goes here.
myStream.Close();
}
}
我不知道我错在哪里，
感谢任何帮助。特纳克斯
I want to read the content of the file opened using file dialog box and then save it in a byte array to pass it to a web service
Stream myStream;
OpenFileDialog saveFileDialog1 = new OpenFileDialog();
saveFileDialog1.Filter = "zip files (*.zip)|*.zip|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
NSITESERVICE.UploadSoapClient obj = new NSITESERVICE.UploadSoapClient();
byte[] filebytes = //what should i pass it over here...
obj.UploadFile("kamal", "p@ssword", filebytes);
// Code to write the stream goes here.
myStream.Close();
}
}
I dont know where i am wrong

您没有为
filebytes变量分配任何内容，因此实际上是将 null 传递给服务。使用 File.ReadAllBytes 方法读取所有字节并将其传递给网络服务。You are not assigning anything to
filebytesvariable so you are essentially passing null to the service. Use File.ReadAllBytes method to read all the bytes and pass it to the webservice.您实际上并没有从 myStream 中读取字节。
You're not actually reading the bytes out of the myStream.
