I've a piece of code:
using (StreamReader stream = new StreamReader(file.OpenRead(), Encoding))
{
char[] buffer = new char[chunksize];
while (stream.Peek() >= 0)
{
int readCount = stream.Read(buffer, 0, chunksize);
yield return new string(buffer, 0, readCount);
}
}
Now i have to surround this with an try-catch block
try
{
using (StreamReader stream = new StreamReader(file.OpenRead(), Encoding))
{
char[] buffer = new char[chunksize];
while (stream.Peek() >= 0)
{
int readCount = stream.Read(buffer, 0, chunksize);
yield return new string(buffer, 0, readCount);
}
}
}
catch (Exception ex)
{
throw ExceptionMapper.Map(ex, file.FullName)
}
I can't see any way to do what i want.
EDIT
The method has the signature
public IEnumerable<string> ReadPieces(int pieces)
I need a try catch
with a call to the ExceptionMapper
in the catch
case.
The method is used deferred by all callers.
The exceptions i have to catch are coming from these calls
File.OpenRead()
stream.Read()
