How Do I change a String Varible into a int varible

Sorry I tried it, it woundent convert the xml string into a int (and the xml string is 19). Maybe this would work if I could make the xml file have some kind of int varible inside it, but how can I do that, I only know basic xml.

so when reading the Xml - how exactly are you reading it? Can you post some code? The way the Integer.Parse works is that you must have the correct string format/which has the values you want which are integer values. Example:

"12345" -> this will work

"abc12345" -> this will not work as there is "abc"

all characters in the string must be of digits - if this makes sense?

if your code has this:

<random>19</random>

this will not convert to integer because of the <random> tags. you need to get the inner/text property of the tag, so only get the 19 part of of it

how are you reading the xml? are you able to give some code on this? you only need the string, which only has the numbers, you wish to convert to integer.

Here is an example on reading an xml document:

hope one of these helps you in some way but would be cool if you can post some code on how you are reading the Xml so we can help you better :-)

I think you maybe confusing yourself :-)

I've given the code on how to convert a string to an integer.

All that needs to be done is to obtain the value, the number (19 in the example). To do this, you need to read the node/element (<random>) to get the value in the tags/that's been set in the tag (<random>)

Again, can you show us the code you are using to read the xml file? :-)

probably is best to post the way you write the xml file (in its fullest) and how you read it. Here is a short but quick example on how I write/read to xml for this example:

write:

XmlTextReader theWriter = new XmlTextWrite(Application.StartupPath + "\\text.xml",null); theWriter.WriteStartDocument(); theWriter.WriteStartElement("random"); theWriter.WriteString("123"); theWriter.WriteEndElement(); theWriter.WriteEndDocument(); theWriter.Close();

the result being when you open the xml file, itll look something like this:

<?xml version="1.0"?><random>123</random>

Similar to your example right? (except the Xml doc declaration)

so reading:

XmlTextReader theReader = new XmlTextReader(Application.StartupPath + "\\test.xml"); while (theReader.Read()) { if (theReader.NodeType == XmlNodeType.Element) { MessageBox.Show("Element name: " + theReader.Name + Environment.NewLine + "Value of string: " + theReader.ReadString()); } } theReader.Close();

Remember, this isnt the only way to read and write to an xml file but for simplicity, I did this.

Now, when reading, it will give me a messagebox showing "Element name: Random Value of string: 123"

that's cool, thats what we want - the 123 part and the way to get that is by the "ReadString()" method of the textReader.

once we got that, then do the whole conversion as stated in my initial reply to convert the string read (123) to an integer.

does this help further or make it confusing? :-)

Again if possible, post the entire code on how you are writing, and reading, the xml file. Would be a big help to us all

you could but its not really recommended as its the incorrect way of reading the xml - you shouldnt need to use things that aren't needed if it can already be done within the Xml classes :-)

whilst the solution is valid, it is just a bit overload/overhead. As they say, there is always more than 1 solution to a problem

I know you told me how to convert a string into a int. I was just woundering how do I make a varible in a xml, and how do I read a varible in a xml file?

When I say write I don't mean program a program to make xml varibles but program it my self.

Just a small question
