我无法用C#读取文件.ini

using System.IO;
using System.Collections.Generic;

Dictionary<string, string> config = new Dictionary<string, string>();

using (StreamReader reader = new StreamReader("config.ini"))
{
    string line;
    while ((line = reader.ReadLine()) != null)
    {
        // 解析每一行的键值对
        string[] parts = line.Split('=');
        if (parts.Length == 2)
        {
            string key = parts[0].Trim();
            string value = parts[1].Trim();
            config[key] = value;
        }
    }
}

string username = config["username"];
string password = config["password"];
