是否可以在运行时检索此值?
我想将值保存在一个地方,并在我的应用程序需要输出我公司的名称时检索它。

这应该这样做:
using System.Reflection;
string company = ((AssemblyCompanyAttribute)Attribute.GetCustomAttribute(
Assembly.GetExecutingAssembly(), typeof(AssemblyCompanyAttribute), false))
.Company;
如果您确实希望将值保留在一个位置并且解决方案中有多个程序集,则可以:
GetEntryAssembly
代替GetExecutingAssembly
并仅在条目大会上设置公司属性,或更好: <强>更新强>
通过@hmemcpy的建议改进了代码,因此它不再需要[0]
。谢谢!

如果您想要一个很好的通用方法来获取程序集Info数据,请尝试以下方法:
public string GetAssemblyAttribute<T>(Func<T, string> value)
where T : Attribute
{
T attribute = (T)Attribute.GetCustomAttribute(Assembly.GetExecutingAssembly(), typeof (T));
return value.Invoke(attribute);
}
所以你可以调用
string title = GetAssemblyAttribute<AssemblyTitleAttribute>(a => a.Title);
string copyright = GetAssemblyAttribute<AssemblyCopyrightAttribute>(a => a.Copyright);
string version = GetAssemblyAttribute<AssemblyVersionAttribute>(a => a.Version);
string description = GetAssemblyAttribute<AssemblyDescriptionAttribute>(a => a.Description);

基于Adam Price的非常优雅的方法 - 使用Mark的正确评论关于它不适用于版本...提出了以下方法 - 一个用于获取当前正在执行的AssemblyInfo属性 - 一个用于获取“调用”程序集的AssemblyInfo属性。
