Solution 1

If you really need that (in most cases you don't) then you have to copy the CString content.
(For simplicity I assume you have a ANSI CString, not a wide character one)

C++

const int SIZE = 256;
char name[SIZE];

strncpy(name, testCStr, SIZE-1);
name[SIZE] = '\0';

Solution 2

If you're not going to modify the string contents, then you can simply cast the CString to a const pointer.

C++

const char * name = (const char *) testCStr;

Or better,

LPCTSTR name = (LPCTSTR) testCStr;

Solution 3

You can use sprintf() function

C++

CString testCStr;

testCStr = "This is an example.";

char * chr = new char[testCStr.GetLength()];

sprintf(chr, "%s", testCStr);

Do you realize your code is flawed?
(Hint: GetLength does not include the string terminator).
Minor (maybe arguable) points:
- If you suggest using new then it would be nice remembering the OP he/her has to eventually call delete.
- sprintf is overkill for such a task.
