How would you count occurences of a string within a string (C#)?

I am reading a file in line by line and need to count the number of tabs that each string contains. How can I get a count of the tabs i.e. \t from the string.

Thanks for your help

Why cast to uint?
Because it has to be a non-negative integer?
Because the function returns uint...
Why does the function return uint and not simply int?
@dtb, to make it explicit that the return value is never less than zero. That's what an unsigned int is for, after all. As far as I understand, things like Count return int in order to be CLS compliant, which is probably not an issue here.
