输入字符串在c＃net int.parse中的格式不正确

Question

I have string which is like this:

string line = "77.139305\t28.795975"

and i seperate the two integers like this:

string lat = line.Substring(0, 9);
string lng = line.Substring(10, 9);

whic exactly seperates the 2 numbers like this: "77.139305" and "28.795975" for lat and lng.

  int latitude,longitude;
   bool result = Int32.TryParse(lat, out latitude);
                  if (result)
                  {
                      col1[i] = latitude;
                      Console.WriteLine("lat: " + col1[i]);
                  }
                  else
                  {
                      if (lat == null) lat = "";
                      Console.WriteLine("Attempted conversion of lat '{0}' failed.", lat);
                  }
                  bool result2 = Int32.TryParse(lng, out longitude);
                  if (result2)
                  {
                      col2[i] = longitude;
                      Console.WriteLine("longit: " + col2[i]);
                  }
                  else
                  {
                      if (lng == null) lng = "";
                      Console.WriteLine("Attempted conversion of lng '{0}' failed.", lng);
                  }

As a result it always excutes else condition and if i don't handle this exception in else condition then it gives "input string was not in a correct format in c# net int.parse" How to solve this problem ?

Answer 1

You are passing in floating point numbers and using an integer parsing method.

Use the Double.Parse parsing method instead.
