用C#建立XML檔案

 以前某項目中需要匯出xml作為fusionChats資料來源，xml貌似本身沒有建立檔案的函數，於是手寫了一個方法

代碼

using System.Text;
using System.IO;
using System.Xml;

namespace BIS.Service
{
public class FileCommand
    {

public static readonly string DataPath = AppDomain.CurrentDomain.BaseDirectory + @"Data\";
/// <summary>
/// 寫出一個檔案
/// </summary>
/// <param name="FileName"></param>
/// <param name="Content"></param>
/// <returns></returns>
        public static bool CreateXML(string FileName, string Content) 
        {
bool isSuccess = false;
//FileName += ".xml";
            FileStream objFileStream = null;
            StreamWriter objStreamWriter = null;
try
            {
//判斷檔案是否已經存在，如果存在即覆蓋
                  if (File.Exists(DataPath + FileName))
                {
                    File.Delete(DataPath + FileName);
                }
                XmlDocument xml = new XmlDocument();
                objFileStream = new FileStream(DataPath + FileName, FileMode.Append, FileAccess.Write);
                objStreamWriter = new StreamWriter(objFileStream, Encoding.Default);
                objStreamWriter.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
                objStreamWriter.WriteLine(Content);  //將字串寫入到檔案中
                isSuccess = true;
            }
catch (Exception e)
            {
//throw new Exception("匯出失敗");
            }
finally
            {
if (objStreamWriter != null)
                {
                    objStreamWriter.Flush(); 
                    objStreamWriter.Close();
                }
            }
return isSuccess;
        }
    }
}
