Pass file to servlet from c#.net application
Jun 2 2009 5:32 AM
I want to pass a file from my c#.net application and I am using WebClient.UploadFile(). I am not sure if this is the best way of doing this. At the moment I cannot access the file content within the servlet - Can anyone help me here?
I have tried to pass the file source (xml) as a String within a nameValueCollection item, however, it seems that it is too long to be added to the collection. As u can see I have also tried to simply upload the String...
Any help would be appreciated...
This is what I have so far....
//upload the file
WebClient client = new WebClient();
//create a collection of values
NameValueCollection nvc;
String fileSource = getFileSource(file);
Console.WriteLine("File Source Is: " + fileSource);
nvc = setCollectionValues(m1, securityToken, file);
try
{
//upload the file to the servlet
//client.UploadFile(url, "post", file);
//client.UploadString(url, fileSource);
//add the header to the request
client.Headers.Add(nvc);
}
catch
{
//log an error here and complete proper exception handling
}
Stream data;
StreamReader reader;
String responseFromServer;
data = client.OpenRead(url);
reader = new StreamReader(data);
responseFromServer = reader.ReadToEnd();
//clean up the streams
reader.Close();
data.Close();
}
private static string getFileSource(String fileName)
{
FileStream file = new FileStream(fileName, FileMode.Open, FileAccess.Read);
StreamReader reader = new StreamReader(file);
String s = reader.ReadToEnd();
reader.Close();
file.Close();
return s;
}
