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

public void Merge(
	Evidence evidence
)

Parameters

evidence
Type: System.Security.Policy.Evidence

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

Exception Condition
ArgumentException

The evidence parameter is not a valid instance of Evidence.

SecurityException

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.

System_CAPS_noteNote

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);
myEvidence.Merge(newEvidence);
Console.WriteLine("Evidence count = " + PrintEvidence(myEvidence).ToString());

SecurityPermission

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
