File name with prefix and number

问题

i have this problem, I want create this filename of xml file:

NOHEL+number.xml

The number is from variable number, where i added +1 always when i send file out. NOHEL is prefix. Exapmle:

NOHEL1.xml
NOHEL2.xml
NOHEL3.xml

And i want give there...

string strFileName = @"C:\\Users\\L\\Desktop\\NOHEL+number.xml";

Have you any ideas?

回答1:

Try this:

string strFileName = @"C:\Users\L\Desktop\NOHEL" + number + ".xml";

By the way, you don't need to escape characters with \ when you have @.

回答2:

You can use

string.Format(@"C:\Users\L\Desktop\NOHEL{0}.xml", number) 

or

@"C:\Users\L\Desktop\NOHEL" + number + ".xml".

And there is no need to make double slash when you use @ symbol.
