Does C# support templates?
No. However, there are plans for C# to support a type of template known as a generic. These generic types have similar syntax but are instantiated at run time as opposed to compile time. You can read more about them here.

How does one compare strings in C#?
In the past, you had to call .ToString() on the strings when using the == or != operators to compare the strings' values. That will still work, but the C# compiler now automatically compares the values instead of the references when the == or != operators are used on string types. If you actually do want to compare references, it can be done as follows: if ((object) str1 == (object) str2) { ... }Here's...

X=X+1 is equivalent to
A) X++B) X+=1C) Both A & B

X=x+1 is equivalent to x+=1 except that value of x is evaluated only once.x=x+1 is not equal to x++ (not always equal as mentioned in one of the earlier comments). If x++ is a standalone statement, the two have equal effect.
