String.replace method

[ace333]

I want to use the .replace() method in the string object to change the \ into a \\ so that instead of hard coding the file path below I can do it dynamically. However when I try the following in c# I get an error
String.Replace("\","\\") because the \ has to be escaped. But if I put \\ it wont find the \ in the string. Bit of a puzzle



File c:\temp\e.xml


XmlTextReader xtr = new XmlTextReader("C:\\temp\\e.xmll);

If you put the @ character before the opening quotes the compiler will read the string literally and you won't have to escape anything. So you could use:

XmlTextReader xtr = new XmlTextReader(@"C:\temp\e.xmll);

Will this work if the string is in a variable name like

mlTextReader xtr = new XmlTextReader(@variableName);

Not sure - I don't have VS installed on this machine. You could try it and see whether it compiles.

If not you can use @ elsewhere, i.e. String.Replace(@"\", @"\\")

I'm a little confused. If you are hard-coding a path, you can use

XmlTextReader xtr = new XmlTextReader(@"C:\temp\e.xml");

// or

XmlTextReader xtr = new XmlTextReader("C:\\temp\\e.xml");

to escape the backslashes. If you already have a path in a variable, you shouldn't need to edit it further.

When you say you want to 'do it dynamically', where are you going to get the dynamic path from? Are you reading it from a file? Building it up from some other data? If you can be more specific about what you are trying to do, we may be able to be more helpful...
