Evidence.Merge Method (Evidence)


Merges the specified evidence set into the current evidence set.

Namespace:   System.Security.Policy
Assembly:  mscorlib (in mscorlib.dll)

public void Merge(
	Evidence evidence


Type: System.Security.Policy.Evidence

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

Exception Condition

The evidence parameter is not a valid instance of Evidence.


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

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.


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.

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


for the ability to manipulate evidence when Locked is true and the evidence parameter has a host list that is not empty. Associated enumeration: SecurityPermissionFlag.ControlEvidence
