組件:

System.Security.Permissions.dll

套件:

來源:

GacMembershipCondition.cs

指示指定的辨識項是否符合成員資格條件。

public:
 virtual bool Check(System::Security::Policy::Evidence ^ evidence);

public bool Check (System.Security.Policy.Evidence evidence);

abstract member Check : System.Security.Policy.Evidence -> bool
override this.Check : System.Security.Policy.Evidence -> bool

Public Function Check (evidence As Evidence) As Boolean

參數

evidence

Evidence

要進行測試的 Evidence。

傳回

Boolean

如果指定的辨識項符合成員資格條件，則為 true，否則為 false。

實作

Check(Evidence)

範例

下列程式代碼範例示範 如何使用 Check 方法。 這個範例是提供給 類別之較大範例的 GacMembershipCondition 一部分。

GacMembershipCondition ^ Gac1 = gcnew GacMembershipCondition;
GacInstalled ^ myGac = gcnew GacInstalled;
try
{
     array<Object^>^hostEvidence = {myGac};
     array<Object^>^assemblyEvidence = {};
     Evidence^ myEvidence = 
         gcnew Evidence(hostEvidence,assemblyEvidence);
     bool retCode = Gac1->Check(myEvidence);
     Console::WriteLine("Result of Check = {0}\n", retCode);
}
catch (Exception^ e) 
{
     Console::WriteLine("Check failed : {0}{1}", Gac1, e);
     return false;
}

GacMembershipCondition Gac1 = new GacMembershipCondition();
GacInstalled myGac = new GacInstalled();
try
{
    Object [] hostEvidence = {myGac};
    Object [] assemblyEvidence = {};

    Evidence myEvidence = new Evidence(hostEvidence,assemblyEvidence);
    bool retCode = Gac1.Check(myEvidence);
    Console.WriteLine("Result of Check = " + retCode.ToString() + "\n");
}
catch (Exception e)
{
    Console.WriteLine("Check failed : " + Gac1.ToString() + e);
    return false;
}

Dim Gac1 As New GacMembershipCondition
Dim myGac As New GacInstalled
Try
    Dim hostEvidence() As Object = {myGac}
    Dim assemblyEvidence() As Object

    Dim myEvidence As New Evidence(hostEvidence, assemblyEvidence)
    Dim retCode As Boolean = Gac1.Check(myEvidence)
    Console.WriteLine(("Result of Check = " & retCode.ToString() _
        & ControlChars.Lf))
Catch e As Exception
    Console.WriteLine(("Check failed : " & Gac1.ToString() & _ 
        e.ToString()))
    Return False
End Try

備註

這個成員資格條件會測試 GacInstalled 辨識項。
