C#程序编译时自动更新版本号方法

C#程序编译时自动更新版本号方法

1.创建控制台工程AutoUpdateVersion，复制如下代码，生成exe文件

    using System;
    using System.IO;
//by txwtech
    namespace AutoUpdateVersion
    {
        class Program
        {
            static void UpdateVersion(ref string line)
            {
                var first = line.IndexOf('"');
                var second = line.LastIndexOf('"');
                var sVersion = line.Substring(first + 1, second - first - 1);
                var arrVersion = sVersion.Split('.');
                if (arrVersion.Length < 4) return;
                var major = Convert.ToInt32(arrVersion[0]);
                var minor = Convert.ToInt32(arrVersion[1]);
                var build = Convert.ToInt32(arrVersion[2]);
                var amendment = Convert.ToInt32(arrVersion[3]);
                if (++amendment > 999) ++build;
                if (build > 99) ++minor;
                if (minor > 9) ++major;
                var sNewVersion = $"{major}.{minor}.{build}.{amendment}";
                line = line.Replace(sVersion, sNewVersion);
            Console.WriteLine("this is updateversion app");
            }

            static void Main(string[] args)
            {
                if (args.Length != 1 || !File.Exists(args[0])) return;
                var lines = File.ReadAllLines(args[0]);
                for (int i = lines.Length - 1; i >= 0; i--)
                {
                    if (lines[i].Contains("assembly: AssemblyFileVersion"))
                    {
                        UpdateVersion(ref lines[i]);
                    }
                    if (lines[i].Contains("assembly: AssemblyVersion") && !lines[i].Contains("*"))
                    {
                        UpdateVersion(ref lines[i]);
                        break;
                    }
                }
                File.WriteAllLines(args[0], lines);
            }
        }
    }

2. 拷贝文件

3.复制到另外一个项目，需要自动更新版本号的项目

4. 打开项目属性进行设置；

start AutoUpdateVersion $(ProjectDir)Properties\AssemblyInfo.cs

或者：

AutoUpdateVersion $(ProjectDir)Properties\AssemblyInfo.cs
