所以我不知道你是否还需要它，但我自己写了。这是我的代码。

在我的测试中它完美无缺。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace Steam_acf_File_Reader
{
    class AcfReader
    {
        public string FileLocation { get; private set; }

        public AcfReader(string FileLocation)
        {
            if (File.Exists(FileLocation))
                this.FileLocation = FileLocation;
            else
                throw new FileNotFoundException("Error", FileLocation);
        }

        public bool CheckIntegrity()
        {
            string Content = File.ReadAllText(FileLocation);
            int quote = Content.Count(x => x == '"');
            int braceleft = Content.Count(x => x == '{');
            int braceright = Content.Count(x => x == '}');

            return ((braceleft == braceright) && (quote % 2 == 0));
        }

        public ACF_Struct ACFFileToStruct()
        {
            return ACFFileToStruct(File.ReadAllText(FileLocation));
        }
