Concat( )

 method that take 

object

 references, rather than 

string

 references. These obtain the string representation of the objects with which they 

are called and return a string containing the concatenation of those strings. (The string 

representations are obtained by calling 

ToString( )

 on the objects.) These versions of 

Concat( )

 are shown here:

public static string Concat(object 

v1

)

public static string Concat(object 

v1

, object 

v2

)

public static string Concat(object 

v1

, object 

v2

, object 

v3

)

public static string Concat(object 

v1

, object 

v2

, object 

v3

, object 

v4

)

public static string Concat(params object[ ] 

v

)

The first method simply returns the string equivalent of 

v1.

 The other methods return a 

string that contains the concatenation of their arguments. The
