C# WPF 使用 [DllImport('kernel32')] 读取 INI 文件内容

可以使用以下代码循环读取ini文件下的内容：

using System.Runtime.InteropServices;
using System.Text;

public static class IniFileHelper
{
    [DllImport('kernel32')]
    private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

    public static string ReadIniFile(string filePath, string section, string key)
    {
        StringBuilder sb = new StringBuilder(255);
        int result = GetPrivateProfileString(section, key, '', sb, 255, filePath);
        return sb.ToString();
    }

    public static List<string> ReadIniFileSection(string filePath, string section)
    {
        List<string> values = new List<string>();
        StringBuilder sb = new StringBuilder(32768);
        int result = GetPrivateProfileString(section, null, null, sb, 32768, filePath);
        string[] lines = sb.ToString().Split(new char[] { '\0' }, StringSplitOptions.RemoveEmptyEntries);
        foreach (string line in lines)
        {
            if (!line.StartsWith(';') && !line.StartsWith('#'))
            {
                int index = line.IndexOf('=');
                if (index > 0)
                {
                    string key = line.Substring(0, index);
                    string value = line.Substring(index + 1);
                    values.Add(value);
                }
            }
        }
        return values;
    }
}

使用方法：

string filePath = 'your ini file path';
string section = '写日志';
string key = '20230421103922946';
string value = IniFileHelper.ReadIniFile(filePath, section, key);

List<string> values = IniFileHelper.ReadIniFileSection(filePath, section);
foreach(string value in values)
{
    // do something with value
}
