Question

Given public String(char*) why we cannot use the following statement?

string str = new string("aaa");

Error 1

The best overloaded method match for
‘string.String(char*)’ has some
invalid
arguments C:\temp\ConsoleApplication2\ConsoleApplication2\Program.cs 19 26 ConsoleApplication2

Error 2

Argument 1: cannot convert from
‘string’ to
‘char*’ C:\temp\ConsoleApplication2\ConsoleApplication2\Program.cs 19 37 ConsoleApplication2

Answer 1

Simply use:

 string str = "aaa";

You do not need to new a string.

“aaa” is a string. It is not a char *.
char * is used with unsafe code.
