質問

この質問にはすでに答えがあります：

クラスライブラリからAssemblyCompanyNameを取得します 4つの回答

実行時にこの値を取得することは可能ですか？

価値を1か所に保持し、アプリケーションが会社の名前を出力する必要があるときはいつでもそれを取得したいと思います。

解決

これはそれをする必要があります：

using System.Reflection;

string company = ((AssemblyCompanyAttribute)Attribute.GetCustomAttribute(
    Assembly.GetExecutingAssembly(), typeof(AssemblyCompanyAttribute), false))
   .Company;

値を1つの場所に保持したい場合、ソリューションに複数のアセンブリがある場合は、次のことができます。

使用する GetEntryAssembly それ以外の GetExecutingAssembly 会社の属性をエントリーアセンブリにのみ設定します。
中央のアセンブリ情報ファイルを使用してくださいこの答え

アップデート@hmemcpyの提案によってコードを改善したので、必要ありません [0] もう。ありがとう！

他のヒント

アセンブリ情報データを取得するための素敵な一般的な方法が必要な場合は、次のことを試してください。

public string GetAssemblyAttribute<T>(Func<T, string> value)
    where T : Attribute
{
    T attribute = (T)Attribute.GetCustomAttribute(Assembly.GetExecutingAssembly(), typeof (T));
    return value.Invoke(attribute);
}

その後、電話をかけることができます

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);

Adam Priceの非常にエレガントな方法に基づいて - マークからの正しいコメントがバージョンで機能していない...次の方法（現在の実行中のAssemblyInfoプロパティを取得するための1つ）と「呼び出し」を取得するための1つの方法を思いつきました。 AssemblyのAssemblyInfoプロパティ。
