Which method it is called on 3.ToString()?
System.Int16.ToString()
System.Int32.ToString()
System.Int64.ToString()
All integer literals in C# default to int (Int32) unless they are too big for int, in which case they become a larger data type that fits, like long(Int64).
So in this case, Int32.ToString() is called.
System.Int32.ToString() as literal integers are Int32 type

Will the C# function Convert.ToInt32(text) convert different words to the same int? Any links or pushes in the right direction are appreciated!
P.S.
What about anagrams?
No, Convert.ToInt32(text) will just try to parse your text to an int, like:
Convert.ToInt32("032") will return 32 as int but
Convert.ToInt32("Brian") will throw an exception.
I assume that you want to have some kind of hashing, when you say "different words to the same int".
Try GetHashCode(). It will return the same value if you call it multiple times with the same value, for example:
"Brian".GetHashCode() will always return 1635321435

I've encountered sometimes code like this and I am kind of new to programming. I want to find out what's the meaning behind those objects or data type enclosed in parenthesis.
(int)
(datagridview)
(form)
If you see something like this it's called a cast. It's used to explicitly convert a data type to another data type.
double pi = 3.14159;
int my_int = (int)pi;
See this description on casting for more details.

How do i create a six digit sequence number in c# ?
Is there any other way than storing a string in the database like "000000" and later on incrementing it through the last inserted value ?
Use a plain old number as a sequence, this is what your DB will provide. If you want to display it with six digits, just call: yourNumber.ToString("D6")
(see docs)

I want to gain a true or false answer if this variable is enable to be converted from string into a int value.
Is there a build-in syntax for it in C#?
Use int.TryParse
string numberString = "123";
int number;
bool isConvertible = int.TryParse(numberString, out number);
