Implements

Check(Evidence)

Examples

The following code example shows the use of the Check method. This example is part of a larger example provided for the GacMembershipCondition class.

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

Remarks

This membership condition tests GacInstalled evidence.
