c# AssemblyInfo 解释 .net 读取项目AssemblyInfo.cs属性值

使用VS创建C#项目（File->New->Project->Visual C#->Class Library）,它会自动为我们产生一个AssemblyInfo.cs文件。在一个实际的项目当中，我们必须修改该文件的内容。How to use the following info: 
AssemblyInfo ainfo = new AssemblyInfo(); 
frmAbout.Text = ainfo.Title; 
frmAbout.menuAbt.Text = string.Format("&About{0}..",ainfo.Title); 
frmAbout.Text = "About " + this.Owner.Text; 
frmAbout.Icon = this.Owner.Icon; 
//You can set the icon like this on the abt form. 
frmAbout.pictureBox1.Image = this.Owner.Icon.ToBitmap(); 
frmAbout.lblTitle.Text = ainfo.Title; 
frmAbout.lblVersion.Text = ainfo.Version; 
frmAbout.lblCopyright.Text = ainfo.Copyright; 
frmAbout.lblDescription.Text = ainfo.Description; 
frmAbout.lblCodebase.Text = ainfo.CodeBase; 
下面是具体的实现代码。
