Özel durumlar

Örnekler

Aşağıdaki örnekte, çağrı sitelerindeki meta veri belirteçlerini ResolveMethod genel ve genel olmayan bağlamlarda çözümlemek için yönteminin iki aşırı yüklemesinin nasıl kullanılacağı gösterilmektedir.

Kod örneği, her biri genel bir yöntemi olan ve G2<Tg2>olmak üzere iki genel türü G1<Tg1> tanımlar. G1<Tg1> ayrıca parametresi için tür parametresini Tg1 kullanan genel olmayan bir yöntemi vardır. türdeki G2<Tg2> genel yöntem GM2<Tgm2> birkaç yöntem çağrısı içerir:

• Olay 1: ve tür bağımsız değişkenleri olarak tür GM2<Tgm2> parametreleri G2<Tg2> kullanılarak genel yöntem GM1<Tgm1> çağrılır. Başka bir deyişle, çağrılan yöntemin parametre türleri için tür tanımından kapalı bir genel tür oluşturmak için G2<Tg2>kullanılan türlere bağlıdır.

• Olay 2: Genel olmayan yöntem M1 çağrılır. Bu yöntemin parametresi, G1<Tg1>bu durumda kapsayan türün tür parametresiyle değiştirilen tanımlama türünün G2<Tg2>tür parametresini kullanır.

• Olay 3: Genel yöntem GM1<Tgm1> çağrılır Int32 , genel türün ve Object genel yöntemin tür bağımsız değişkenleri için sırasıyla ve belirtilir. Bu yöntem çağrısı, kapsayan türün veya yöntemin tür parametrelerine bağlı değildir.

• Olay 4: Sınıfının genel olmayan yöntemi M1Example çağrılır. Bu yöntem çağrısı, kapsayan türün veya yöntemin tür parametrelerine bağlı değildir.

Buna ek olarak, örnek genel Example olmayan sınıfı tanımlar. Bu sınıfın genel bir yönteme M çağrı yapan bir yöntemi vardır.

• Olay 5: Genel yöntem GM1<Tgm1> çağrılır Int32 , genel türün ve Object genel yöntemin tür bağımsız değişkenleri için sırasıyla ve belirtilir. Bu yöntemin bağlamı kapsayan genel türe veya genel yönteme sahip değildir.

Her durumda, örnek önce çağrılan yöntemi temsil eden bir MethodInfo oluşturur ve ardından ve parametrelerinin değerlerini almak için genericMethodArgumentsgenericTypeArguments ve MethodInfo.GetGenericArguments yöntemlerini kullanarak yöntem aşırı yüklemesini Type.GetGenericArguments kullanarak belirteci ResolveMethod(Int32, Type[], Type[]) çözümler. Yöntemler genel olmayan bağlamlar için döndüreceği Type.EmptyTypes için bu teknik her durumda çalışır. Örnek, çözümlenen MethodInfo ile yapısını karşılaştırır MethodInfo.

Örnek daha sonra belirteci çözümlemek için yöntem aşırı yüklemesini kullanmayı ResolveMethod(Int32) dener. Yöntem çağrıları genel bağlama bağlı olmadığından bu durum 3, 4 ve 5 durumlarında çalışır. 1 ve 2 durumlarında, belirteci çözümlemek için yeterli bilgi olmadığından bir özel durum oluşur.

Meta veri belirteci değerleri sabit numaralandırma olarak kodlanmıştır. Bu kod örneğini değiştirirseniz, belirteç değerleri büyük olasılıkla değişir. Yeni belirteç değerlerini belirlemek için kodu derleyin ve derlemeyi incelemek için /TOKENS seçeneğiyle Ildasm.exe kullanın. Belirteçler çağrı noktalarında bulunabilir. Yeni değerleri sabit listesi içine ekleyin ve örneği yeniden derle.

Açıklamalar

Type.GetGenericArguments için genel tür bağımsız değişkenlerinden oluşan bir dizi elde etmek üzere genericTypeArgumentskapsamdaki metadataToken türünde yöntemini kullanın. MethodInfo.GetGenericArguments için genel tür bağımsız değişkenlerinden oluşan bir dizi elde etmek için genericMethodArgumentskapsamın içinde olduğu metadataToken yönteminde yöntemini kullanın. Gerekli olmadığında bile bu bağımsız değişkenleri sağlamak her zaman güvenlidir.

Özel durumlar

Örnekler

Aşağıdaki örnekte, çağrı sitelerindeki meta veri belirteçlerini ResolveMethod genel ve genel olmayan bağlamlarda çözümlemek için yönteminin iki aşırı yüklemesinin nasıl kullanılacağı gösterilmektedir.

Kod örneği, G1<Tg1> her biri genel bir yönteme sahip olan iki genel türü ve G2<Tg2> (G1(Of Tg1) ve G2(Of Tg2) Visual Basic'te) tanımlar. G1<Tg1> ayrıca parametresi için tür parametresini Tg1 kullanan genel olmayan bir yöntemi vardır. türdeki G2<Tg2> genel yöntem GM2<Tgm2> birkaç yöntem çağrısı içerir:

• Olay 1: ve tür bağımsız değişkenleri olarak tür GM2<Tgm2> parametreleri G2<Tg2> kullanılarak genel yöntem GM1<Tgm1> çağrılır. Başka bir deyişle, çağrılan yöntemin parametre türleri için tür tanımından kapalı bir genel tür oluşturmak için G2<Tg2>kullanılan türlere bağlıdır.

• Olay 2: Genel olmayan yöntem M1 çağrılır. Bu yöntemin parametresi, G1<Tg1>bu durumda kapsayan türün tür parametresiyle değiştirilen tanımlama türünün G2<Tg2>tür parametresini kullanır.

• Olay 3: Genel yöntem GM1<Tgm1> çağrılır Int32 , genel türün ve Object genel yöntemin tür bağımsız değişkenleri için sırasıyla ve belirtilir. Bu yöntem çağrısı, kapsayan türün veya yöntemin tür parametrelerine bağlı değildir.

• Olay 4: Sınıfının genel olmayan yöntemi M1Example çağrılır. Bu yöntem çağrısı, kapsayan türün veya yöntemin tür parametrelerine bağlı değildir.

Buna ek olarak, örnek genel Example olmayan sınıfı tanımlar. Bu sınıf, genel bir yönteme M çağrı yapan bir yönteme sahiptir:

• Olay 5: Genel yöntem GM1 çağrılır Int32 , genel türün ve Object genel yöntemin tür bağımsız değişkenleri için sırasıyla ve belirtilir. Bu yöntemin bağlamı kapsayan genel türe veya genel yönteme sahip değildir.

Her durumda, örnek önce çağrılan yöntemi temsil eden bir MethodInfo oluşturur ve ardından ve parametrelerinin değerlerini almak için genericMethodArgumentsgenericTypeArguments ve MethodInfo.GetGenericArguments yöntemlerini kullanarak yöntem aşırı yüklemesini Type.GetGenericArguments kullanarak belirteci ResolveMethod(Int32, Type[], Type[]) çözümler. Yöntemler genel olmayan bağlamlar için döndüreceği Type.EmptyTypes için bu teknik her durumda çalışır. Örnek, çözümlenen MethodInfo ile yapısını karşılaştırır MethodInfo.

Örnek daha sonra belirteci çözümlemek için yöntem aşırı yüklemesini kullanmayı ResolveMethod(Int32) dener. Yöntem çağrıları genel bağlama bağlı olmadığından bu durum 3, 4 ve 5 durumlarında çalışır. 1 ve 2 durumlarında, belirteci çözümlemek için yeterli bilgi olmadığından bir özel durum oluşur.

Meta veri belirteci değerleri sabit numaralandırma olarak kodlanmıştır. Bu kod örneğini değiştirirseniz, belirteç değerleri büyük olasılıkla değişir. Yeni belirteç değerlerini belirlemek için kodu derleyin ve derlemeyi incelemek için /TOKENS seçeneğiyle Ildasm.exe kullanın. Belirteçler çağrı noktalarında bulunabilir. Yeni değerleri sabit listesi içine ekleyin ve örneği yeniden derle.
