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

由 二次信任 提交于 2020-07-18 21:44:13
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 I am absolutely new to programming. I'm trying to create a very simple app with three TextBoxes and one final TextBlock. I want to save the input from these three TextBoxes locally so I can read and display it in a TextBlock on the bottom of the page in one string. I have read that the StreamWriter class is what I should be using. I just don't know where to start...

问题 I have some XML in a XMLDocument and I want to put it into a StringWriter , but it always becomes empty(?) instead.

Here's what I have: XmlDocument xmlInput = new XmlDocument(); /* after this executes, xmlInput has lots of data in it */ xmlInput.LoadXml(...); XslCompiledTransform transform = new XslCompiledTransform(); /* I'm pretty sure Template.xslt is being found and loaded correctly */ transform

C# Compact Framework - OutOfMemoryException with XmlSerializer.Serialize

由 此生再无相见时 提交于 2019-12-04 16:47:44
I'm trying to serialize a large collection of objects (20,000) objects within the collection.

It looks like it should work, but CF does have unpredictable limitations. Is xml a requirement? I can't remember trying it with 20k records, but another option might
