As highlighted by Tilendor in Jon Skeet's answer, streams have a CopyTo
method since .NET 4.
var fileStream = File.Create("C:\\Path\\To\\File");
myOtherObject.InputStream.Seek(0, SeekOrigin.Begin);
myOtherObject.InputStream.CopyTo(fileStream);
fileStream.Close();
Or with the using
syntax:
using (var fileStream = File.Create("C:\\Path\\To\\File"))
{
myOtherObject.InputStream.Seek(0, SeekOrigin.Begin);
myOtherObject.InputStream.CopyTo(fileStream);
}
