Question

我的项目树（解决方案资源管理器）包含一个名为Configs的文件夹（它直接位于根目录中）。如何从中读取文件 - 我已经尝试过

string ss1 = File.ReadAllText("\\..\\..\\Configs\\Settings.txt");

但是没有这样的文件（路径的一部分）

如果您想获取项目文件夹，请转到一个级别，以下语言扩展方法应该适合您。

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
public static class Extensions
{
    /// <summary>
    /// Given a folder name return all parents according to level
    /// </summary>
    /// <param name="FolderName">Sub-folder name</param>
    /// <param name="level">Level to move up the folder chain</param>
    /// <returns>List of folders dependent on level parameter</returns>
    public static string UpperFolder(this string FolderName, Int32 level)
    {
        List<string> folderList = new List<string>();

        while (!string.IsNullOrEmpty(FolderName))
        {
            var temp = Directory.GetParent(FolderName);
            if (temp == null)
            {
                break;
            }
            FolderName = Directory.GetParent(FolderName).FullName;
            folderList.Add(FolderName);
        }

        if (folderList.Count > 0 && level > 0)
        {
            if (level - 1 <= folderList.Count - 1)
            {
                return folderList[level - 1];
            }
            else
            {
                return FolderName;
            }
        }
        else
        {
            return FolderName;
        }
    }
    public static string CurrentProjectFolder(this string sender)
    {
        return sender.UpperFolder(3);
    }
}

用法

string configurationFile = 
    Path
    .Combine(AppDomain.CurrentDomain.BaseDirectory.CurrentProjectFolder(), "Configs");

if (File.Exists(configurationFile))
{
    string fileContents = File.ReadAllText(configurationFile);
}

从项目目录中的文件夹中读取文件
