exColor 作为示例，可能过于简单

这里再补充一个 ini 解析的示例

由于实在写不动用其他库解析 ini 了, 春节都要过完了，累了，写不动了，

所以随意找了一份解析ini的库， 仅供参考，对比不准确，毕竟完整库包含了更多功能
先看看结果

总结

delegate 肯定会有调用消耗，ini 场景使用的函数远多于 HexColor ，可以看到消耗大了很多

先看来自 dotnet Microsoft.Extensions.Configuration 中解析 ini 的代码

public static IDictionary<string, string?> Read(string content)
{
var data = new Dictionary<string, string?>(StringComparer.OrdinalIgnoreCase);
using (var reader = new StringReader(content))
{
string sectionPrefix = string.Empty;

    while (reader.Peek() != -1)
    {
