C＃中获取程序集版本号的方法

最简单的办法：
string version = Assembly.GetExecutingAssembly().GetName().Version.ToString();

方法一：
public void GetFileVersion() {
FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(Path路径字符串);
string AssmblyVersion=myFileVersionInfo.FileVersion;
}

方法二：
[assembly: AssemblyTitle("")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]
修改AssemblyInfo.cs文件的上述信息

在程序中调用如下：
Version ApplicationVersion = new Version(Application.ProductVersion);
string AssmblyVersion = ApplicationVersion.Major;//获取主版本号

方法三：
private void GetEdition()
{
Assembly assembly = Assembly.GetExecutingAssembly();
//this.labelEdition.Text = assembly.FullName;

// 获取程序集元数据
AssemblyCopyrightAttribute copyright = (AssemblyCopyrightAttribute)
AssemblyCopyrightAttribute.GetCustomAttribute(Assembly.GetExecutingAssembly(),
typeof(AssemblyCopyrightAttribute));
AssemblyDescriptionAttribute description = (AssemblyDescriptionAttribute)
AssemblyDescriptionAttribute.GetCustomAttribute(System.Reflection.Assembly.GetExecutingAssembly(),
typeof(AssemblyDescriptionAttribute));

string a = description.Description;
string b = description.Description;
string c = copyright.Copyright;
string d = Application.ProductVersion;
}

方法四：
string path = @"C:\WINNT\Microsoft.NET\Framework\v1.1.4322\System.dll";
Assembly assembly = Assembly.LoadFile(path);
AssemblyName assemblyName = assembly.GetName();
Version version = assemblyName.Version;
Console.WriteLine(assemblyName.FullName);
string a=version.Major.ToString();
string b= version.Minor.ToString();
string c=version.Revision.ToString();
string d=version.Build.ToString();

只要得到Assembly ，剩下的都好说，可以看看Assembly的几个静态方法，应该可以满足所有需要了。比如//得到Mscorlib.dll Assembly.GetAssembly(typeof(string))
