C# 操作INI文件类
先Show示例：
private void TestINI_Load(object sender, System.EventArgs e)
{
//创建一个INIFile对象，参数为文件路径，如果不存在它会自动创建的
INIFile inf=new INIFile(@"D:\工作目录\VSPP\VSPPServer\bin\Debug\COMPILED.INI");
//显示INI配置的结构
foreach(string k in inf.Segments.Keys)
{
TreeNode o=new TreeNode(k);
INISegment s=inf.Segments[k]; //取出当前配置节
foreach(string k1 in s.Items.Keys)
{
TreeNode o1=new TreeNode(k1+" = "+s.Items[k1].Value); //访问配置节中每个配置项
o.Nodes.Add(o1);
}
treeView1.Nodes.Add(o);
}
//添加一个配置
inf.Segments.Add("Test"); //添加Test节
www.Syue.com
inf.Segments["Test"].Items.Add("IP","192.168.0.1"); //添加一个配置项
//快速添加一个配置项
inf.Segments["测试"].Items["Host"].Value="localhost"; // ：）和上面两行一样的效果
//读取也是同样的方便
MessageBox.Show(inf.Segments["测试"].Items["Host"].Value);
//如果不存在这样的配置项，将返回空字符串并创建这个项
MessageBox.Show(inf.Segments["测试"].Items["Server"].Value);
//清除一个配置节下面的所有配置项
//inf.Segments["Action"].Clear();
}
