C implementation code to determine whether a string is full or half Angle

The full Angle of the C# string is a character represented by 2 bytes

The half Angle of the C# string is 1 character represented by 1 byte

. So we can use string length and System text. Encoding. Default. Judging GetByteCount

Where string. length represents the number of characters in the C# string string,

System. text. Encoding. Default. GetByteCount said the number of bytes of the string.

Half Angle is judged as follows:

if (checkString.Length == Encoding.Default.GetByteCount(checkString)) 
{       
   return true;      
}     
else    
{      
   return false;     
}

The full Angle is determined as follows:

if (2 * checkString.Length == Encoding.Default.GetByteCount(checkString))  
 {      
   return true;   
 }     
 else    
 {      
   return false;    
}

This achieves the purpose of determining whether the C# string is full Angle or half Angle.
