c# - overriding ToString() with formating arguments -

this question has answer here:

• how pass variables overridden tostring() method? 4 answers

consider scenario:

 int mynumber = 10;  string formattednumber = mynumber.tostring("0000"); // output "0010" 

ie., can format integer using tostring() in above code. have class named mynewclass in over-riding tostring(), aim formatted output using overrided tostring() method.

 public class mynewclass         {             public int myproperty { get; set; }             public mynewclass(dynamic x)             {                 myproperty = x;             }             public override string tostring()             {                 return myproperty.tostring();             }         } 

now creating object of class as:

 mynewclass p = new mynewclass(10); 

when called tostring() formatting wont compile:

  var m = p.tostring("0000");//gives error "no overloaded method tostring() takes 1 argument." 

so have changed function signature following:

  public override string tostring(string format)         {             return myproperty.tostring(format);         } 

again result in same as: no suitable method found override

my question how can achieve overriding tostring() formating arguments

remove override keyword , you're set. you're not overriding in case since system.object has string tostring(). you're doing adding additional function call existing 1 (just numeric value types in framework itself).
