C# – Best way to change the value of an element in C#

.netc++xml

I'm trying to look at the best way of changing the value of an element in XML.

<MyXmlType>
   <MyXmlElement>Value</MyXmlElement>
</MyXmlType>

What is the easiest and/or best way to change "Value" in C#?

I've looked at XMLDocument and it will cause a load of the whole XML document to memory. Could you do it safely with the XMLReader. The problem is changing the value and emitting it back seems like an interesting conundrum.

Cheers 😀

Best Solution

You could use the System.Xml.Linq namespace stuff for the easiest to read code. This will load the full file into memory.

XDocument xdoc = XDocument.Load("file.xml");
var element = xdoc.Elements("MyXmlElement").Single();
element.Value = "foo";
xdoc.Save("file.xml");

C# – the difference between String and string in C#

string is an alias in C# for System.String.
So technically, there is no difference. It's like int vs. System.Int32.

As far as guidelines, it's generally recommended to use string any time you're referring to an object.

e.g.

string place = "world";

Likewise, I think it's generally recommended to use String if you need to refer specifically to the class.

e.g.

string greet = String.Format("Hello {0}!", place);

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

C# – Calling the base constructor in C#

Modify your constructor to the following so that it calls the base class constructor properly:

public class MyExceptionClass : Exception
{
    public MyExceptionClass(string message, string extrainfo) : base(message)
    {
        //other stuff here
    }
}

Note that a constructor is not something that you can call anytime within a method. That's the reason you're getting errors in your call in the constructor body.
