I have a class which is using XmlConvert to convert relevant datatype data in to string.Now XmlConvert has method ToString to convert int,decimal,byte data in to string but its overload doesnt have byte[].

public class StringConverter 
{
   public virtual string ToString(byte[] value) => XmlConvert.ToString(value); //Error
}

Update : Reason why i am using XmlConvert class to convert data to string is to make this conversion locale independent

Since i am tying to use XmlConvert class to convert byte[] to string in locale independent so this is not a duplicate because i have already gone through couple of links below :

How do you convert a byte array to a hexadecimal string, and vice versa?

How to convert UTF-8 byte[] to string?

It is not possible to use XmlConvert class to convert byte[] to string?

  • @WaiHaLee I have already checked this link and i am trying to convert byte[] to string in locale independent using xmlconvert class so its not a duplicate Commented Feb 8, 2019 at 7:19

    Please define what you mean by "locale independent"? Some encodings work better for some locales (due to the support character set) that is a matter of encoding choice, the actual conversion (Encoding.GetString()`) is the same. Commented Feb 8, 2019 at 8:10

If you want to convert bytes to a string, you have to use some encoding. There's no one-size-fits-all encoding that works all the time, and so XmlConvert is not going to solve this problem for you.

But nowadays, UTF-8 is the defacto standard, so if you're not sure which one to use, that may be your best bet.

virtual string ToString(byte[] value) => System.Text.Encoding.UTF8.GetString(value);

How about this : BitConverter.ToString(ba).Replace("-",""); as given here stackoverflow.com/questions/311165/…
@Learning-Overthinker-Confused That will convert the bits to a hexadecimal string. Is that what you're trying to do?
Actually i am trying read varbinary,binary,image datatype type data from sql server using data reader from database and the answer in your code was throwing error with image datatype byte[] conversion to string
@Learning-Overthinker-Confused The line in my answer is for converting a byte array representing readable text to a string of readable text. An image is another matter. If you want to represent images as strings, you have to clarify how you intend to represent them. Hexadecimal? Base64?
@Learning-Overthinker-Confused Yeah, because the requirement of "I want to represent an image as a string" makes no sense on its own. You have to figure out what it means in your case to "represent an image as a string". There are various ways of representing binary values as strings (two of which I listed). You need to decide what you intend to use in your case. Until you figure out what your actual requirements are, nobody here can help you.

Why did use need XmlConvert? Did you try this?

virtual string ToString(byte[] value) => System.Text.Encoding.Default.GetString(value);
