[筆記本]

記錄以前在VB時候常常呼叫API，現在改成使用 Visual Studio 2010撰寫時呼叫API方法有些小小改變，今日就將他記下來。

首先將開啟記事本撰寫所要讀取與寫入的值，在將記事本另存新檔副檔名為.ini。

 

 

引用必要條件

using System.Runtime.InteropServices;

設定必要API

 [DllImport("kernel32")]
        private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

 

Read .ini File 

private void button2_Click(object sender, EventArgs e)
        {
            //Read ini File
            OpenFileDialog Open = new OpenFileDialog();
            Open.ShowDialog();

            StringBuilder retVal = new StringBuilder(255);  //回傳所要接收的值

            
            string Section = "His name 2";
            string Key = "Thread name 3";
            string Defaut = "null";      //如果沒有 Section , Key 兩個參數值，則將此值賦給變量
            int Size = 255;              //設定回傳 Siez 
                         
            int strref = GetPrivateProfileString(Section, Key, Defaut, retVal, Size, Open.FileName);

            Console.WriteLine("Return Value {0}", retVal);
        }

write .ini File

private void button1_Click(object sender, EventArgs e)
        {   //Write ini File
            OpenFileDialog Open = new OpenFileDialog();
            Open.ShowDialog();

            string Section = "His name 2";
            string Key = "Thread name 3";
            string Value = "Value 8888";

            WritePrivateProfileString(Section, Key, Value, Open.FileName);

        }
