System.IO.StreamWriter寫文件

public void WriteFile(string filepath, List<string> list)

{

    int index = 0;

    System.IO.FileStream fileStream = new System.IO.FileStream(filepath,System.IO.FileMode.Create);

    System.IO.StreamWriter streamWriter = new System.IO.StreamWriter(fileStream);

    //streamWriter.Write(content);

    streamWriter.Flush();

    streamWriter.BaseStream.Seek(0,System.IO.SeekOrigin.Begin);

    list.ForEach(item => {

        streamWriter.WriteLine("第"+(index++)+"條記錄->"+item);

    });

    streamWriter.Flush();

    streamWriter.Close();

    fileStream.Close();
