There are a few ways to do this     Using char struct  to string and back again   string  stringOfA   char ConvertFromUtf32 65    int  asciiOfA   char ConvertToUtf32  A   0     Simply casting the value  char and string shown   char  charA    char 65   string  stringA     char 65  ToString      Using ASCIIEncoding  This can be used in a loop to do a whole array of bytes  var  bytearray   new byte     65     ASCIIEncoding  asiiencode   new ASCIIEncoding     string  alpha    asiiencode  GetString  newByte  0  1     You can override the type converter class  this would allow you to do some fancy validation of the values   var  converter   new ASCIIConverter     string  stringA    string  converter ConvertFrom 65    int  intOfA    int  converter ConvertTo  A   typeof int      Here is the Class   public class ASCIIConverter   TypeConverter          Overrides the CanConvertFrom method of TypeConverter         The ITypeDescriptorContext interface provides the context for the        conversion  Typically  this interface is used at design time to         provide information about the design-time container      public override bool CanConvertFrom ITypeDescriptorContext context         Type sourceType                if  sourceType    typeof string                         return true                    return base CanConvertFrom context  sourceType              public override bool CanConvertTo ITypeDescriptorContext context  Type destinationType                if  destinationType    typeof int                         return true                    return base CanConvertTo context  destinationType                  Overrides the ConvertFrom method of TypeConverter      public override object ConvertFrom ITypeDescriptorContext context         CultureInfo culture  object value                 if  value is int                          you can validate a range of int values here               for instance                if  value  gt   48  amp  amp  value  lt   57                throw error               end if              return char ConvertFromUtf32 65                     return base ConvertFrom context  culture  value                 Overrides the ConvertTo method of TypeConverter      public override object ConvertTo ITypeDescriptorContext context         CultureInfo culture  object value  Type destinationType                if  destinationType    typeof int                         return char ConvertToUtf32  string value  0                     return base ConvertTo context  culture  value  destinationType

Here s a function that works for all 256 bytes  and ensures you ll see a character for each value   static char asciiSymbol  byte val         if  val  lt  32   return          Non-printable ASCII     if  val  lt  127   return  char val       Normal ASCII        Workaround the hole in Latin-1 code page     if  val    127   return          if  val  lt  0x90   return                                          val  amp  0xF        if  val  lt  0xA0   return                                            val  amp  0xF        if  val    0xAD   return           Soft hyphen  this symbol is zero-width even in monospace fonts     return  char val       Normal Latin-1
