than one value (like int and string[] ) and from that function.

Hi Dear AssanKhan Ismail,

You can return more than one (1) value or type by constructing a class and
returning that class in your function.

for example:
========

Construct a class like this with 4 Different Types like bool, int, double,
string

public class Different_Types
{
public Different_Types ()
{
//
// TODO: Add constructor logic here
//
}

int m_int;
string m_str;
bool m_bool;
double m_double;

public int PassInteger
{
get {return m_int;}
set {m_int = value;}
}

public string PassString
{
get {return m_str;}
set {m_str = value;}
}
public bool PassBoolean
{
get {return m_bool;}
set {m_bool = value;}
}
public double PassDouble
{
get {return m_double;}
set {m_double = value;}
}
}

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Then Create you Function which return 4 Different Types of Values ( but all
the 4 different types of values pass through the object which is created the
class above

function name is = Returen_Many_Va lues_CLASS

it returns the type of object = Different_Types
for this object you have created a class above

public Different_Types Returen_Many_Va lues_CLASS()
{
Different_Types diff_types = new Different_Types ();
diff_types.Pass Boolean=false;
diff_types.Pass Double=3.142;
diff_types.Pass Integer=67;
diff_types.Pass String="Venkat" ;
return diff_types;
}

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Use the above function in a button click and populate 4 different textboxes

for this you have to place 4 different textboxes and one command button

private void button1_Click(o bject sender, System.EventArg s e)
{
this.textBox1.T ext=Returen_Man y_Values_CLASS( ).PassBoolean.T oString();
this.textBox2.T ext=Returen_Man y_Values_CLASS( ).PassDouble.To String();
this.textBox3.T ext=Returen_Man y_Values_CLASS( ).PassInteger.T oString();
this.textBox4.T ext=Returen_Man y_Values_CLASS( ).PassString;

}

You can test this one in one dummy windows application in .net

Hi Dear AssanKhan Ismail,

You can even do with struct

for that first create a struct like below

struct MyStruct
{
public int x;
public string y;
}
------------------------------------------------------------------------------------------------
then create you function which returns you struct

private MyStruct MyStruct_Return ing_Method()
{
MyStruct ms = new MyStruct();
ms.x=121;
ms.y="venkat";
return ms;
}

Name of the Function=MyStru ct_Returning_Me thod
Return type=MyStruct

Give value to both the type like int and string (I have given as 121 &
"venkat")

------------------------------------------------------------------------------------------------

Place two textboxex and one command button on the windows form to test

In the button click event write this code
private void button1_Click(o bject sender, System.EventArg s e)
{
this.textBox1.T ext=MyStruct_Re turning_Method( ).x.ToString();
this.textBox2.T ext=MyStruct_Re turning_Method( ).y;
}

Test and for anything and everything, please let me know
