The following code works correctly for me public class Foo { public static void Main() { var myPage = “test string”; var repo = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes(myPage)); } } It seems that the correct way to do this is to create the MemoryStream using the default constructor var repo = new System.IO.MemoryStream(); and then write to … Read more
Here is the sample code. System.IO.MemoryStream ms = new System.IO.MemoryStream(); System.IO.StreamWriter writer = new System.IO.StreamWriter(ms); writer.Write(“Hello its my sample file”); writer.Flush(); writer.Dispose(); ms.Position = 0; System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Plain); System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(ms, ct); attach.ContentDisposition.FileName = “myFile.txt”; // I guess you know how to send email with an attachment // after sending email … Read more
Yes, you should delete the space between <? and xml. <?xml version=”1.0″ encoding=”utf-8″ ?> <form> <e order=”0″ type=”custom” name=”test”> <fi type=”text” /> <o /> </e> <e order=”1″ type=”zip” /> <e order=”2″ type=”state” /> </form> Here’s the relevant XML spec.
The answer is in the GetBuffer() MSDN doc, you might have missed it. When you create a MemoryStream without providing a byte array (byte[]) : it creates an expandable capacity initialized to zero. In other words, the MemoryStream will reference to a byte[] with the proper size when a Write call will be made on … Read more
No, it’s not. using ensures that Dispose() will be called, which in turn calls the Close() method. You can assume that all kinds of Streams are getting closed by the using statement. From MSDN: When you use an object that accesses unmanaged resources, such as a StreamWriter, a good practice is to create the instance … Read more
You are forgetting to flush your StreamWriter instance. public static Stream Foo() { var memStream = new MemoryStream(); var streamWriter = new StreamWriter(memStream); for (int i = 0; i < 6; i++) streamWriter.WriteLine(“TEST”); streamWriter.Flush(); <– need this memStream.Seek(0, SeekOrigin.Begin); return memStream; } Also note that StreamWriter is supposed to be disposed of, since it implements … Read more
You need to reset the position of the stream before copying. outStream.Position = 0; outStream.CopyTo(fileStream); You used the outStream when saving the file using the imageFactory. That function populated the outStream. While populating the outStream the position is set to the end of the populated area. That is so that when you keep on writing … Read more
This code works for me: public void Run() { Dog myDog = new Dog(); myDog.Name= “Foo”; myDog.Color = DogColor.Brown; System.Console.WriteLine(“{0}”, myDog.ToString()); MemoryStream stream = SerializeToStream(myDog); Dog newDog = (Dog)DeserializeFromStream(stream); System.Console.WriteLine(“{0}”, newDog.ToString()); } Where the types are like this: [Serializable] public enum DogColor { Brown, Black, Mottled } [Serializable] public class Dog { public String Name … Read more
If you’d checked the results of stream.Read, you’d have seen that it hadn’t read anything – because you haven’t rewound the stream. (You could do this with stream.Position = 0;.) However, it’s easier to just call ToArray: settingsString = LocalEncoding.GetString(stream.ToArray()); (You’ll need to change the type of stream from Stream to MemoryStream, but that’s okay … Read more
Why do you need resetting memory stream? You always can create a new one. Or you can use: memoryStream.SetLength(0);
