c# - How to create a string from a char array

Create string from char array

The following asp.net c# example code demonstrate us how can we create a string object from a char array programmatically at run time in an asp.net application. Char array represent an array whose each element value represent a single Unicode character.

.Net framework's String Class has several constructors to initialize a new String Class (string object). String Class String(Char[]) constructor allow us to initialize a new instance of the String Class to the value indicated by an array of Unicode characters (char array). We just need to pass a char array object as a parameter of this constructor.

Finally, we can create a string object from a char array by this way String Newstring = new String(CharArray). The newly created string contains the value populated from specified char array values (Unicode characters).
