wpf中读写配置文档的方法

WPF配置文件读取与写入:

1、 在程序根目录下新建文本文档,将后缀名改成.ini文件;(将已存在的Param.dat的后缀改成。ini

譬如:Param.ini

1) 文档的写法:INI文件由节、键、值组成。

2、 VS项目中新建类:INIFile.cs

 

    class INIFile

    {

        private string filePath;

 

        [DllImport("kernel32")]

        private static extern long WritePrivateProfileString(string strSection, string strKey, string strVal, string strFilePath);

        

        [DllImport("kernel32")]

        private static extern int GetPrivateProfileString(string strSection, string strKey, string strDef, StringBuilder sbRetVal, int intSize, string strFilePath);

        

        public INIFile(string strFilePath)

        {

            this.filePath = strFilePath;

        }           

        

        public void Write(string strSection, string strKey, string strValue)

        {

            WritePrivateProfileString(strSection, strKey, strValue, this.filePath);

        }

 

        public string Read(string strSection, string strKey)

        {

            StringBuilder sb = new StringBuilder(255);

            int i = GetPrivateProfileString(strSection, strKey, "", sb, 255, this.filePath);

            return sb.ToString();

        }                   

 

        public string FilePath

        {

            get { return this.filePath; }

            set { this.filePath = value; }

        }

    }

3、 调用类方法:

//定义

INIFile INI_Param = new INIFile(Environment.CurrentDirectory + @"\Param.ini");

 

//读取配置文档参数

private bool ReadParam()

        {

            try

            {

                float buff;

                //ActionLog.WriteLog("Read Setting Information...");

                buff = Convert.ToSingle(INI_Param.Read("SysParam", "Range"));

                rangeTb.Text = buff.ToString();

                buff = Convert.ToSingle(INI_Param.Read("SysParam", "Grade"));

                comboBox.Text = buff.ToString();

                buff = Convert.ToSingle(INI_Param.Read("SysParam", "MarginError"));

                marginErrorTxt.Text = buff.ToString();                         

                return true;

            }

            catch(Exception ex)

            {

                ErrorLog.WriteLog("读取参数失败:" + ex.Message.ToString());

                return false;

            }

        }

//读取工位信息

private List<string> readStation()

        {

            List<string> stationInfo = new List<string>();            

            stationInfo.Add(INI_Param.Read("StationInfo", "Station1"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station2"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station3"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station4"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station5"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station6"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station7"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station8"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station9"));

            stationInfo.Add(INI_Param.Read("StationInfo", "Station10"));

            return stationInfo;

        }

//将数据更新到配置文档中

        private void UpdateParam()

        {

            try

            {

                string buff;

                buff = rangeTb.Text;

                INI_Param.Write("SysParam", "Range", buff);

 

                buff = comboBox.Text;

                INI_Param.Write("SysParam", "Grade", buff);

 

                buff = marginErrorTxt.Text;

                INI_Param.Write("SysParam", "MarginError", buff);

            }

            catch(Exception ex)

            {

                ErrorLog.WriteLog("写入参数失败:" + ex.Message.ToString());

            }

        }
