I have a base 64 string like this:

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

I want to convert this string to normal string

Please, can any one help me?

I have already used two methods:
1:

byte[] encodedDataAsBytes
                = System.Convert.FromBase64String(data);
            string returnValue =
               System.Text.ASCIIEncoding.ASCII.GetString(encodedDataAsBytes);
            return returnValue;

2:

byte[] b = Convert.FromBase64String(data);
 string strOriginal = System.Text.Encoding.UTF8.GetString(b);
 return strOriginal;

but this methods not converting into normal format of string

Where did you get the string you want to convert, and are you really sure it is only base64-converted? Is the text written in arabic encoding?

Solution 1

ASCII encoding and UTF decoding?!

Use following instead-

C#

public string DecodeBase64String(string encodedData)
{
byte[] encodedDataAsBytes = System.Convert.FromBase64String(encodedData);
string returnValue = System.Text.ASCIIEncoding.ASCII.GetString(encodedDataAsBytes);
return returnValue;
}
