这里给大家讲解一下在winform环境下如何读写ini配置文件
读取Ini文件主要用到了如下的IniClass.cs库，然后直接调用即可
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
namespace ReadIni
{
public class IniClass
{
public string iniPath;
[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);
/// <summary>
/// 构造方法
/// </summary>
/// <param name="IniPath">文件路径</param>
public IniClass(string iniPath)
{
this.iniPath = iniPath;
}
/// <summary>
/// 写入INI文件
/// </summary>
/// <param name="Section">项目名称(如 [TypeName] )</param>
/// <param name="Key">键</param>
/// <param name="Value">值</param>
public void IniWriteValue(string Section, string Key, string Value)
{
WritePrivateProfileString(Section, Key, Value, this.iniPath);
}
/// <summary>
/// 读出INI文件
/// </summary>
/// <param name="Section">项目名称(如 [TypeName] )</param>
/// <param name="Key">键</param>
public string IniReadValue(string Section, string Key)
{
StringBuilder temp = new StringBuilder(500);
int i = GetPrivateProfileString(Section, Key, "", temp, 500, this.iniPath);
return temp.ToString();
}
/// <summary>
/// 验证文件是否存在
/// </summary>
/// <returns>布尔值</returns>
public bool ExistIniFile()
{
return File.Exists(iniPath);
}
}
}/// <summary>
/// 读配置
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
IniClass Db = new IniClass(Application.StartupPath + @"\test.ini");
string a = Db.IniReadValue("USER", "user");
string b = Db.IniReadValue("USER", "passwd");
}
/// <summary>
/// 写配置
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{
string fPath = Path.Combine(Application.StartupPath + @"\test.ini");
IniClass Db = new IniClass(fPath);
Db.IniWriteValue("USER", "user", "admin");
Db.IniWriteValue("USER", "passwd", "123456");
}[USER]
user=admin
passwd=123456
