Updating xml using linq married dating in sorento illinois
In the previous post, you learned how to create an xml file from a collection of Book objects with Linq. Save("d:/data.xml"); To delete an element from the xml file, you need to select the element based on your conditions. However, we don't guarantee all things of the web are accurate.
Now, you will learn how to read, add, edit, and delete elements of the xml file that is stored in your computer. Then you will use the Remove method of the XElement class to delete that element. If you find any error, please report it then we will take actions to correct it as soon as possible.
Map Path("data.xml")); var items = from item in xml Doc. It seems to me there should be better usage guidelines.
Value == item ID select new foreach (var item in items) "; XDocument xml Doc = XDocument. I've seen junior developers get it into their heads that you need a To List or To Array after every single query regardless of usage. Map Path("data.xml")); var items = (from item in xml Doc.
You can use the Nodes-Method on XElement and check manually.
But i will advise you to use the XPath Evaluate-Extension Method For XPath expression take a look at: How to check if an element exists in the xml using xpath?
If you do not first materialize them into a list, or if you do not use the extension methods, it is possible to encounter a certain class of bugs.I want to access the savegame by Id Number (these numbers are unique) Then I want to change the value of balance (for example to 50) and then save these changes to my document. These are the controls I am using in my code: ERROR : Error 1 'bool' does not contain a definition for ' Element' and no extension method ' Element' accepting a first argument of type 'bool' could be found (are you missing a using directive or an assembly reference? I got stuck at the very first point of it i.e i cant grab the value from xml file using linq. , which only contains 2 strings, name and description. Then I populate a new list, which contains many of the same names, but some of them contains descriptions that the other list did not contain.
