linq-to-xml

问题 Hope you can help me a bit. I'm trying to write to an XML file, but am struggling to write the method which, well, writes to the XML file. This is the XML file manually written (using Notepad++ etc.): <software> <software_entry name="Adobe Acrobat X Standard" path="Applications\Acrobat\Acrobat X Standard\AcroStan.msi" type="msi" switches="/qn ALLUSERS=1" /> <software_entry name="Adobe Acrobat X Professional" path="Applications\Acrobat\Acrobat X Pro\AcroPro.msi" type="msi" switches="/qn

问题 What advantages are there for using either XSLT or Linq to XML for HTML parsing in C#? This is under the assumption that the html has been cleaned so it is valid xhtml. These values will eventually go into a c# object to be validated and processed. Please let me know if these are valid and if there are other things to consider. XSLT Advantages: Easy to change quickly and deploy Fairly well known XSLT Disadvantages: Not compiled, so is slower to process String manipulation can be cumbersome

问题 Hi I’m trying to use a DataGridView for the first time and with LINQ. Here’s what I’m trying to do: I want to use it (although it doesn’t have to the DataGridView ) to read and display the contents of an XML file (this bit is working code below) but I want to have an add row button on the form or in the DataGridView that takes the contents of three textboxes and and populates the contents of three columns of the new row. The new row is to be appended to the existing data. Next I would like to

问题 I have an application in which I am using XPathNavigator to iterate nodes. It is working fine. But I want to know that if I use LINQ to Xml.... What benefits(Performance, maintainability) I will get? With XPath, LINQ to Xml what is the performance hit? I am using C#.net, VS 2010 and my .xml is mid size. 回答1: Well, XPathNavigator will generally be faster than Linq to XML queries. But there's always 'but'. Linq to XML will definitely make your code more readable and maintainable. It's easier
