Parameters

evidence: Evidence

The evidence set to be merged into the current evidence set.

The evidence parameter is not a valid instance of Evidence.

SecurityException

Locked is true, the code that calls this method does not have ControlEvidence, and the evidence parameter has a host list that is not empty.

Examples

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

Console::WriteLine( "\nMerge new evidence with the current evidence." );
array<Object^>^oa1 = {};
Site^ site = gcnew Site( "www.wideworldimporters.com" );
array<Object^>^oa2 = {url,site};
Evidence^ newEvidence = gcnew Evidence( oa1,oa2 );
myEvidence->Merge( newEvidence );
Console::WriteLine( "Evidence count = {0}", PrintEvidence( myEvidence ) );

Console.WriteLine("\nMerge new evidence with the current evidence.");
Object [] oa1 = {};
Site site = new Site("www.wideworldimporters.com");
Object [] oa2 = { url, site };
Evidence newEvidence = new Evidence(oa1, oa2);
myEvidence.Merge(newEvidence);
Console.WriteLine("Evidence count = " + PrintEvidence(myEvidence).ToString());

Console.WriteLine(ControlChars.Lf & "Merge new evidence with the current evidence.")
Dim oa1() As [Object]
Dim site As New Site("www.wideworldimporters.com")
Dim oa2 As [Object]() = {url, site}
Dim newEvidence As New Evidence(oa1, oa2)
myEvidence.Merge(newEvidence)

Console.WriteLine(("Evidence count = " & PrintEvidence(myEvidence).ToString()))

Remarks

Each evidence object in the specified evidence set is added to the assembly and host sets of the current evidence set, according to the sets from which it came.

Note

This method does not perform a check to prevent adding duplicate types of evidence. Many assembly and host evidence objects can exist at the same time.
