Solution:
You might have not disposed while reading/writing.
Use either of these two:
1.
StreamWriter objStreamWriterUp = null;
TextReader objTextReaderUp = null;
try
{
using (objTextReaderUp = new StreamReader(sourceFilePath))
{
using (objStreamWriterUp
= new StreamWriter(destiFilePath, !blIsFirstTimeCl))
{
//your code
}
}
}
catch (Exception ex)
{
throw;
}
finally
{
if (objStreamWriterUp != null)
{
objStreamWriterUp.Dispose();
}
}
2.
StreamWriter objStreamWriterUp = null;
TextReader objTextReaderUp = null;
try
{
objTextReaderUp = new StreamReader(sourceFilePath);
objStreamWriterUp = new StreamWriter(destiFilePath, !blIsFirstTimeCl);
//your code
}
catch (Exception ex)
{
throw;
}
finally
{
if (objTextReaderUp != null)
{
objTextReaderUp.Dispose();
}
if (objStreamWriterUp != null)
{
objStreamWriterUp.Dispose();
}
}
