C#读取文件:按行读取

C#如何读取文件前面说过了:http://blog.csdn.net/yysyangyangyangshan/article/details/6948327,下面以一个例子来说明如何按行读取,其实很简单,就是使用FileStream的ReadLine()方法。
例如有这样一个文件test.txt,读取出来显示在一个richtextbox中,文件内容如下:
诺基亚    =N8  摩托罗拉  =ME525+  华为   =HONOR  HTC=A3366/T9299
读取方法为:
 public static Dictionary<string, string> ReadLineFile()          {              string filePath = Common.StartupPath + @"test.txt";                Dictionary<string, string> contentDictionary = new Dictionary<string, string>();                if (!File.Exists(filePath))              {                  return contentDictionary;              }                FileStream fileStream = null;                StreamReader streamReader = null;                try              {                  fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);                    streamReader = new StreamReader(fileStream, Encoding.Default);                    fileStream.Seek(0, SeekOrigin.Begin);                    string content = streamReader.ReadLine();                    while (content != null)                  {                      if (content.Contains("="))                      {                          string key = content.Substring(0, content.LastIndexOf("=")).Trim();                            string value = content.Substring(content.LastIndexOf("=") + 1).Trim();                            if (!contentDictionary.ContainsKey(key))                          {                              contentDictionary.Add(key, value);                          }                      }                      content = streamReader.ReadLine();                  }              }              catch              {              }              finally              {                  if (fileStream != null)                  {                      fileStream.Close();                  }                  if (streamReader != null)                  {                      streamReader.Close();                  }              }              return contentDictionary;          }
