C#创建并读取ini文件

1、首先导入命名空间：using System.Runtime.InteropServices;//引用DllImport

using System.Text;//引用StringBuilder

2、声明API函数

[DllImport("kernel32")]

private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);

3、创建ini文件

WritePrivateProfileString("MyAccount", "ID", "30643300", @"D:\Account.ini");

WritePrivateProfileString("MyAccount", "PWD", "**********", @"D:\Account.ini");

4、声明API函数

[DllImport("kernel32")]

private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

5、读取ini文件

StringBuilder temp = new StringBuilder();

GetPrivateProfileString("MyAccount", "ID", "账号错误", temp, 255, @"D:\Account.ini");

string ID = temp.ToString();

GetPrivateProfileString("MyAccount", "PWD", "读取出错", temp, 255, @"D:\Account.ini");

string PWD = temp.ToString();

MessageBox.Show(ID + ":" + PWD);
