            sLat1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr1).InnerText;

            sLong2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr2).InnerText;
            sLat2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr2).InnerText;

            Label1.Text = sLong1 + ", " + sLat1;
            Label2.Text = sLong2 + ", " + sLat2;

            elong1 = Convert.ToDouble(sLong1);
            elat1 = Convert.ToDouble(sLat1);
            elong2 = Convert.ToDouble(sLong2);
            elat2 = Convert.ToDouble(sLat2);
        }
        else {
            Label1.Text = "Input Valid values";
        }

}
        double distLong = elong1 * (Math.PI / 180.0);
        double distlat = elat1 * (Math.PI / 180.0);
        double distLong1 = elong2 * (Math.PI / 180.0);
        double distlat1 = elat2 * (Math.PI / 180.0);

in my code i want to have a function called added function...
i used namespace to make this as a function

in my code i'm calling this elong1, elat1, elong2, elat2
so values to out side from this code...
so it gives me an error............
outside of the function elong and elat set not working
because it says not assigned values?

but it gives me an error.
so how i'm gonna do that.......
have any idea?

namespace != function declaration. Declare your functions inside of classes.

What you are trying to achieve is not clear. Please clarify.

thing is i have some values from out side out side
String Strt_Address = TextBox1.Text;
String End_Address = TextBox2.Text;

i gave a if condition to check if the textbox is null or not

if (Strt_Address != null)
{
sLong1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr1).InnerText;
sLat1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr1).InnerText;

sLong2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr2).InnerText;
sLat2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr2).InnerText;

Label1.Text = sLong1 + ", " + sLat1;
Label2.Text = sLong2 + ", " + sLat2;

elong1 = Convert.ToDouble(sLong1);
elat1 = Convert.ToDouble(sLat1);
elong2 = Convert.ToDouble(sLong2);
elat2 = Convert.ToDouble(sLat2);
}
else {
Label1.Text = "Input Valid values";
}

and i want to get all the elong1 elat1 elong2 elat2 values to out side

double distLong = elong1 * (Math.PI / 180.0);
double distlat = elat1 * (Math.PI / 180.0);
double distLong1 = elong2 * (Math.PI / 180.0);
double distlat1 = elat2 * (Math.PI / 180.0);

i declared this aftr my if condition
but this it sho0ws me error that elong1 elat1 elong2 elat2 values are null?

so how i'm do that.........

Try this way may be it works

C#

namespace Addedfunction
        {
        if (Strt_Address != null)
        {
            sLong1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr1).InnerText;
            sLat1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr1).InnerText;
 
            sLong2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr2).InnerText;
            sLat2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr2).InnerText;
 
            Label1.Text = sLong1 + ", " + sLat1;
            Label2.Text = sLong2 + ", " + sLat2;
 
            elong1 = Convert.ToDouble(sLong1);
            elat1 = Convert.ToDouble(sLat1);
            elong2 = Convert.ToDouble(sLong2);
            elat2 = Convert.ToDouble(sLat2);
        }
        else {
            Label1.Text = "Input Valid values";
        }
 

        double distLong = elong1 * (Math.PI / 180.0);
        double distlat = elat1 * (Math.PI / 180.0);
        double distLong1 = elong2 * (Math.PI / 180.0);
        double distlat1 = elat2 * (Math.PI / 180.0);
}

Other wise elong,elat1,elong2,elat2 need to be declare globally..
