INI文件读取帮助

项目中时常会用到不少的外部配置参数,又或者对一些CODE预先定义.使用INI文件来存储不失为一个好办法

 

public class INIHelper
{

        /// <summary>
        /// 读取INI文件专用类
        /// </summary>
        private bool succeeded = false;
        private Hashtable cfgParam = new Hashtable();

        public bool Succeeded { get { return succeeded; } }
        public string this[string ParamName]
        {
            get
            {
                if (cfgParam.ContainsKey(ParamName))
                    return cfgParam[ParamName].ToString();
                else
                    return "";
            }
        }

        public int Length
        {
            get { return cfgParam.Count; }
        }
        /// <summary>
        /// 读取指定INI文件中的配置信息
        /// </summary>
        /// <param name="file">配置文件的完整路径名</param>
        /// <param name="section">配置文件中的节名</param>
        public DbConfig(string file, string section)
        {
            string Section = "[" + section + "]";
            string fileName = file.Substring(file.LastIndexOf('\\') + 1);

            GetInitializeConfig(file, Section);

            //如果MainSysinfoPath不为空，则从MainSysinfoPath指定的文件中读取配置信息
            if (this.succeeded && cfgParam.Contains("MainSysinfoPath"))
            {
                string path = this["MainSysinfoPath"].TrimEnd('\\');    //允许路径尾部带反斜杆“\”或不带反斜杆“\”
                if (path != "") GetInitializeConfig(path + @"\" + fileName, Section);
            }
        }

        private void GetInitializeConfig(string filePath, string Section)
        {
            try
            {
                StreamReader sr = new StreamReader(filePath, System.Text.Encoding.Default);
                string readLine = null;
                bool readEnd = false;
                string[] keyWord;

                while ((readLine = sr.ReadLine()) != null)
                {
                    if (readLine == Section)   //是指定的节，则开始读取配置信息
                    {
                        while ((readLine = sr.ReadLine()) != null)
                        {
                            if (readLine != "")   //跳过空行
                            {
                                if (readLine.Substring(0, 1) == "[")   //是另一新节，则结束本次的读取
                                {
                                    readEnd = true;
                                    break;
                                }

                                keyWord = readLine.Split('=');
                                cfgParam[keyWord[0].Trim()] = keyWord[1].Trim();
                            }
                        }
                    }

                    if (readEnd == true) break;
                }
                sr.Close();
                succeeded = true;
            }
            catch
            {
                succeeded = false;
            }
        }
    }

 

读取速度不错....当然别弄个几百M的配置文件哦....
