With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution

The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it.

C# .NET - Quickest way to split a large file....

Asked by gcargile in C# Programming Language

What is the quickest way to take a large text file and split it up into an array, then output it to a rtb? Is StreamReader the best? Is my rdRead.ReadToEnd() appropriate? There has to be a faster way....ugh

private void btnOpen_Click(object sender, System.EventArgs e)
{
      string myStr;
      AnsiManip.AnsiMain sp = new AnsiManip.AnsiMain();

      Stream rdStream = new FileStream(@"C:\myfile.txt", FileMode.Open);
      BufferedStream rdBuff = new BufferedStream(rdStream);

      StreamReader rdRead = new StreamReader(rdBuff);

      myStr = sp.SplitClaims(rdRead.ReadToEnd(),sep); //This is where it takes forever...

      richTextBox1.Text=myStr;

      rdRead.Close();
      rdBuff.Close();
      rdStream.Close();
}
-----------------------------------------------------------------------------------
using System;

namespace AnsiManip
{
      public class AnsiMain
      {
      public string msg;
      public string SplitClaims(string stringToSplit, char[]sep)
      {
            Array a = stringToSplit.Split(sep);
            for(int i = 0; i < a.Length; i++)
            {
            msg += (a.GetValue(i).ToString());
            }
      return msg;
      }

      }
}
