Object type to int,how?

[FlyBoy]

i have the following code,which im trying (for educational purposes only) convert an object type to int...this is the code:

class test

{

public test(object obj)

{

int tmp;

try

{

tmp=Int32.Parse(obj);;

x=tmp;

}

catch (System.Exception ex)

{

}

 

}

.

.

.

.

.

.

it doesnt work..tried also : int.prase(obj). and still didnt work...any idea?

If the variable really does contain and int then you can simply do

int tmp = (int) obj;

 

This will only work if obj is really an int (not a string that contains a number etc)

thats why im using error catch handlers....

this mathod called Casting right? (never figured what is the diffrence bwtween this,and the method i've tried.) :o

[PlausiblyDamp]

In .Net all data types are ultimately derived from object; therefore a variable declared as object can hold any datatype.

Casting is merely the process of taking a generic representation (i.e. object or a base class if inheritance is being used) and creating a more specific variable to represent it.

 

Things like int.Parse() will convert between two different types of variables i.e. a string that may contain an integer represented as a string andan actual integer.

For a cross-language solution, you can also use the static methods of the Convert

class (i.e. Convert.ToInt32(), in this case).
