Why does string.format("{0:-10}") give off different results on different PCs

I have a line of code in my application that writes some string values to an XmlElement and applies some padding using string formating.

string.Format("{开发者_运维技巧0:-10}{1:-10}{2:-10}", i.Department, i.Category, i.Item)

The outcome for this should be a 30 character string with the Department, Category and Item values.

So this works on our server but not on my local machine. What would cause this to stop working?

Use , instead of : - that's the correct syntax:

string.Format("{0,-10}{1,-10}{2,-10}", i.Department, i.Category, i.Item)

These ways will work safely in any environment.

string.Format("{0}:-10{1}:-10{2}:-10", i.Department, i.Category, i.Item, ":-") 

OR

string.Format("{0}{3}{1}{3}{2}{3}", i.Department, i.Category, i.Item, ":-10") 

If you are going to do padding do as below. Have a look here for more details on padding formats.

string.Format("{0}{3,-10}{1}{3,-10}{2} {3,-10}", i.Department, i.Category, i.Item, ":")
