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))
