Closed 5 years ago.
Consider the following code snippet in C#
string s = "hi";
object k="hi".Substring(0);
// 1>
k==s // true
// 2>
Object.ReferenceEquals(s,k) //true
but when,
Object k="hii".Substring(0,2);
// 1>
k==s // false
// 2>
Object.ReferenceEquals(s,k) //false
I am having difficulty understanding why in the first case, the strings were interned while it doesn't happen so in the second case.
Also it would be very helpful if anyone can point out the rules when string interning happens in c#.

Is there a string math evaluator in .NET?
(18 answers)
Closed 4 years ago.
I have one scenario in C#, which I fetch the expression from database, I need to parse and evaluate the same
The expression can be of any type (With + & - Operator only) as mentioned below
X+Y-Z
X-Y-Z
Z-Y+Z
Where as at run time I have any of above expression as string item and the values for each variable defined in it.
Now I need to automate the same, so that my code at run time will able to parse and evaluate the same.
I believe Switch case and if/else loop is the one way, but any can please suggest some other better and efficient way.
Thanks in advance

I saw this answer, The problem is - so I also need to know what type of encoder to use for getting the correct string - it may be in UTF\UTF8\ANSI.
Here is a example from the immediate window.
Encoding.Unicode.GetString(combinedBuf)
"믯ힿ힜힕�"
Encoding.UTF8.GetString(combinedBuf)
"שלום"

String vs string in C#
I have a test in C# code I'm reading:
if (variable is string)
I am wondering if this is strictly equivalent to:
if (variable is String)
or if some esoteric behavior of C# autoboxing may cause these tests to behave differently.
They are exactly the same - string is an alias for System.String.
