How to convert java Long to c#

public String encrypt(String plaintext) throws Exception {
MessageDigest md = null;

md = MessageDigest.getInstance("SHA");

md.update(plaintext.getBytes("UTF-8"));

byte raw[] = md.digest();

String hash = (new BASE64Encoder()).encode(raw);

return hash;
}

If you're in a 32 bit OS you may need to use ToInt32 (I can't double-check right now but as a long is 32 bits on a 32 bit OS, a 64 bit long in C# will probably fail the type checking).

Also what is "getCreateDate()" ?   If it's an object, it'll need to implement the IConvertible interface and define how it gets converted to an Int64.  

If it's a regular 32 bit long... no conversion needed.  

I tried in C# ...

plainText i.e String doesn't contain definition for getBytes("UTF-8")

Please advice...

What's the return type of this.getCreateDate()?

@Kelaros:

I got the same error when I use Int32. getCreateDate() is a String of 80 characters in length.

@wdosanjos:

this.getCreateDate() returns a String

Please provide some sample values returned by this.getCreateDate().

I think the Java and the C# versions of this.getCreateDate() are returning different values, because the Java's new Long(this.getCreateDate()) would throw a NumberFormatException exception if the value returned by this.getCreateDate() is not a long.

This solution works for me....
