c# - XML - Serialize class - Some questions -

-

I have the idea of ​​serializing the properties of a class in an XML-file and then uploading this file to the server The reason for this is that I want to download this file again and read the serialized content.

Then this kind of structure:

file exists (myfile.xml) - & gt; Serialize the file in data from class (myclass.cs) - & gt; Upload file.

Now the content may look something like this: 

   
 Now the problem is, I do not know how to walk. I want the new data to be serialed in the next way, but it should be linked to that XML-file, not a new one. So I download this file and then I serialize the new data as an attachment so that it will look like this:  
    
 And it should be repeated many times as I want: download file, serial new data and attach it together, then upload it again. Now, the second issue is, I want to read it.  
 I also use XML-class for this. For the type of ultimate type, the data should be serialized, I set the square in which the assets are. But now, there are more nodes of the same name in my XML. I want to separate it now, therefore, not just a class, but a new class with the same name for each node.  
 To show you that a little bit is clear:  
 We have the first couple in XML (some properties, some propertybased). It should now be deserialized on myclass.cs, which has the correct properties for XML-nodes. Example:  
  Public Class MyClass {Public Version SomeProperty {get; Set;} public string SomeProeprtiesChild {get; Set;}}   
 and then the first XML-pair must be distritted to that class. But I want to do this for each XML- "pair" in my XML file, but in my head I can not find the right structure. Should I make a list here or how should I do this? I really hope that I can clarify it clearly, it is very difficult to explain. Apart from this, I do not know how to engage with it. any suggestion?  
 If you have any questions,  Ask !   
 
 
 What you see is not just a serialization. Do you want to sort the same object more than once?  
 A possible solution  list  to be serialized and if the file exists, then the list includes new instances. / P>

python - Writing Greek in matplotlib labels, titles -

Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
