Obtaining Values in a string

Hi All,

This is such a silly question, but how would i obtain the two values lat and lang in the string below, im looking at the two lat and lang values in center.

viewport: {center: {lat: 51.381443,lng: -2.357483},span: {lat: 0.089989,lng: 0.144182},

Thanks

Nick

I would use regular expressions to parse the results out of the string.

The old fashioned way...

String input = "viewport: {center: {lat: 51.381443,lng: -2.357483},span: {lat: 0.089989,lng: 0.144182},";

decimal lat = 0;
decimal lng = 0;

int center = input.IndexOf("center:");
int leftBrace = input.IndexOf("{", center);
int rightBrace = input.IndexOf("}", center);
String data = input.Substring(leftBrace + 1, rightBrace - leftBrace - 1);

String[] values = data.Split(",".ToCharArray());

String[] decimalValue = values[0].Split(":".ToCharArray());
lat = decimal.Parse(decimalValue[1]);

decimalValue = values[1].Split(":".ToCharArray());
lng = decimal.Parse(decimalValue[1]);

MessageBox.Show(lat.ToString() + Environment.NewLine + lng.ToString());

Awsome guys, thanks alot.. i changed it slightly.. as its much quicker now.

Regex regVal = new Regex(@"center: {lat: ([-0-9.]*),lng: ([-0-9.]*)},", RegexOptions.IgnoreCase|RegexOptions.Compiled);

Many thanks Nick
