I want to upload a image to my server form iPhone To upload image my code is
UIImage *image = [UIImage imageNamed:@"bg_DName.png"];
NSMutableData *imageData = (NSData*)UIImagePNGRepresentation(image);
NSString *string = [NSString stringWithFormat:@"http://myServer/HeritageWebServices/Service.asmx/testuploadimage"];
[self setRequest1:[ASIFormDataRequest requestWithURL:[NSURL URLWithString:string]]];
[request1 setPostValue:@"test" forKey:@"value1"];
[request1 setPostValue:@"test" forKey:@"value2"];
[request1 setPostValue:@"test" forKey:@"value3"];
[request1 setTimeOutSeconds:20];
[request1 setDelegate:self];
[request1 setDidFailSelector:@selector(uploadFailed:)];
[request1 setDidFinishSelector:@selector(uploadFinished:)];
[request1 setPostBody:imageData];
// NSLog(@"image %@",imageData);
[request1 setData:imageData withFileName:@"photo.png" andContentType:@"image/png" forKey:@"photo"];
[request1 startAsynchronous];
With the above code i am not able upload image.
UIImage *image = [UIImage imageNamed:@"bg.png"];
NSData *imageData = UIImagePNGRepresentation(image);
//NSLog(@"imageData %@",imageData);
NSString *dt = [[imageData description] stringByTrimmingCharactersInSet:
[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
dt = [dt stringByReplacingOccurrencesOfString:@" " withString:@""];
NSString *string = [NSString stringWithFormat:@"http://myServer/HeritageWebServices/Service.asmx/testuploadimage?image=%@",dt];
// NSLog(@"urlstring %@",string);
request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:string]];
//
[request startAsynchronous];
If i try like this i can upload small image but not large images.Here i am sending the image in the request parameter as string.
My c# code to receive image
[WebMethod]
public byte[] testuploadimage(string image)
{
byte[] imageBytes;

httpWebRequest.ContentLength = image.Length;

login.AppendChild(dec);
XmlElement root = login.CreateElement("CreateUser");
login.AppendChild(root);
//try
//{

string s = image.Replace(" ", string.Empty);
ErrLogMgr.LogErrorMessage(string.Format("{0}{1}", "testuploadimage() for the image :",
image), "testUploadimage Inputs",

}
private byte[] HexStringToByteArray(string hexString)
{
int bytesCount = (hexString.Length) / 2;
byte[] bytes = new byte[bytesCount];
for (int x = 0; x < bytesCount; ++x)
{
bytes[x] = Convert.ToByte(hexString.Substring(x * 2, 2), 16);
}
return bytes;
}
}
For the large image exception which i am getting on server is
System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+. at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams) at System.Drawing.Image.Save(String filename, ImageFormat format) at System.Drawing.Image.Save(String filename) at Heritage.Service.testuploadimage(String image) –</p>
Can anybody help me.. What am i doing wrong Is the problem with my iPhone code of with my c# code. Thanx!!!
