Convert ByteArray to Integer

I want to convert Byte array values to Integers and check for some specific value.

My byte array suppose contains bytes like -> FF 2 3 25 10 etc. How do I check if the value is FF or 10 etc. ?
An example which failed ->

QByteArray ba; 

int i ; 
for( i = 0; i < ba.size(); i++ ) 


{ 
if (ba[i] == 255){ 
//Do Something 

} 
}



This gives the error


C:/Users/vinay/Prog/telnetpro/telnetpro/telnetpro.cpp:61: error: ISO C++ says that these are ambiguous, even though the worst conversion for the first is better than the worst conversion for the second:


The error is for the line [/i]

if (ba[i] == 255){[/i]
