Is there a TextWriter child class that fires event if text is written?

阅读更多关于 Is there a TextWriter child class that fires event if text is written?

问题 I have written a method that accepts a TextWriter as an argument (Usually Console.Out, but not necessarily). When I call this method, some progress info is written to the TextWriter. However, since this method can run a long time, I want to update my UI with some status information. Currently, I am using a StringWriter but it does not have any events. So the first time I get a result from the StringWriter is after the method completed. Now I am searching for a class that inherits from

问题 Merged with How to free up memory after base64 convert. Thanks for your great suggestions to an OOM (out of memory) problem I'm seeing in code intended to stream files for web services. [I hope it is OK to start another thread which provides a bit more detail.] From the suggestions, I shrunk the buffer size used to read from the file, and it looks like memory consumption is better, but I'm still seeing an OOM problem, and I'm seeing this problem with files sizes as small as 5MB. I potentially

Writing Unix style text file in C#

I'm trying to write a text file with Unix-style newlines with my C# program. For some reason the following code doesn't work: TextWriter fileTW = ... fileTW.NewLine = "\n"; fileTW.WriteLine("Hello World!"); Neither does this: TextWriter fileTW = ... fileTW.Write("Hello World! + \n"); In both cases the '\n' is being replaced with '\r\n', which I don't want!

My TextWriter was writing to a MemoryStream, which was then being added to a tar
