Adds the supplied assembly to the list of assemblies that are trusted to execute in the current AppDomain.

Namespace: Microsoft.Reporting.WinForms
Assembly: Microsoft.ReportViewer.WinForms (in microsoft.reportviewer.winforms.dll)

Syntax

'Declaration
'Usage

Parameter

assemblyName
The name of the assembly to be added.

Hinweise

Expressions in the report will be run in the current AppDomain with only the Execution security permission flag. By default, custom assemblies are not allowed in this mode. The AddTrustedCodeModuleInCurrentAppDomain can be used to allow the use of custom assemblies in the current AppDomain.

The name of the assembly passed in the assemblyName parameter should match that specified in the CodeModule element of the report definition file.

Beispiel

In this example, a custom assembly containing a simple utility function that calculates factorials is used as an expression in a report.

using System.IO;
using System.Reflection;

public class Util
{
    public static int Factorial(int n)
    {
        return ((n <= 1) ? 1 : (n * Factorial(n - 1))); 
    }
}

The following code is used to add the custom assembly to the current AppDomain.

reportViewer.LocalReport.ReportPath = "Report1.rdlc";

reportViewer.LocalReport.AddTrustedCodeModuleInCurrentAppDomain("Contoso.Utilities, 
      Version=1.0.271.0, Culture=neutral, PublicKeyToken=89012dab8080cc90");
