StringBuilder and byte conversion

Question

I have the following code:

StringBuilder data = new StringBuilder(); for (int i = 0; i < bytes1; i++) {      data.Append("a");  } byte[] buffer = Encoding.ASCII.GetBytes(data); 

But I get this error:

cannot convert from 'System.Text.StringBuilder' to 'char[]' The best overloaded method match for 'System.Text.Encoding.GetBytes(char[])' has some invalid arguments 

Answer 1

The following code will fix your issue.

StringBuilder data = new StringBuilder(); for (int i = 0; i < bytes1; i++) { data.Append("a"); } byte[] buffer = Encoding.ASCII.GetBytes(data.ToString()); 

The problem is that you are passing a StringBuilder to the GetBytes function when you need to passing the string result from the StringBuilder.
