The Visual C++ System::String class does not support greater than and less than operators (312844)

MORE INFORMATION

The following Visual C++ example demonstrates how to compare two strings:

//compiler option : cl /clr
#using <mscorlib.dll>
#include <tchar.h>

using namespace System;

// This is the entry point for this application.
int _tmain(void)
{
    
  String* myString= "1234";
			
  int rc = myString->CompareTo("abcd");
  
						
  if (rc>0)
	Console::WriteLine("1234 is greater than abcd"); 
			
   else if (rc==0)
	Console::WriteLine("1234 is equal to abcd");

   else
	Console::WriteLine("1234 is less than abcd");


  return 0;
}
				

Note You must add the common language runtime support compiler option (/clr:oldSyntax) in Visual C++ 2005 to successfully compile the previous code sample. To add the common language runtime support compiler option in Visual C++ 2005, follow these steps:

1. Click Project, and then click <ProjectName> Properties.
   
   Note <ProjectName> is a placeholder for the name of the project.
2. Expand Configuration Properties, and then click General.
3. Click to select Common Language Runtime Support, Old Syntax (/clr:oldSyntax) in the Common Language Runtime support project setting in the right pane, click Apply, and then click OK.
