Article
09/02/2015

Sets the base permissions for the sandboxed application domain with the supplied permission set.

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

Syntax

public void SetBasePermissionsForSandboxAppDomain(
    PermissionSet permissions
)

public:
void SetBasePermissionsForSandboxAppDomain(
    PermissionSet^ permissions
)

member SetBasePermissionsForSandboxAppDomain : 
        permissions:PermissionSet -> unit

Public Sub SetBasePermissionsForSandboxAppDomain (
    permissions As PermissionSet
)

Parameters

permissions
Type: System.Security.PermissionSet

The PermissionSet to set. The default base permission is Execution.

Remarks

The base permissions in the sandboxed application domain apply to custom code assemblies and the evaluation of report expressions. Note that this method replaces any existing base permission set with the supplied permission set. You should make sure that the supplied permission set includes the Execution permission. Otherwise, no custom code assemblies can be executed and no expressions can be evaluated.

If you change the permissions, make sure that the LocalReport object cannot be used to access any untrusted report definitions. In .NET Framework 3.5 (or in .NET Framework 4 with enabled), you must explicitly call the ExecuteReportInSandboxAppDomain method to switch to the sandboxed application domain mode.

Examples

Legacy Code Example

The following code adds file input and output permissions to the default base permission set.

PermissionSet permissions = new PermissionSet(PermissionState.None);
permissions.AddPermission(new FileIOPermission(PermissionState.Unrestricted));
permissions.AddPermission(new SecurityPermission(SecurityPermissionFlag.Execution));

ReportViewer1.LocalReport.SetBasePermissionForSandboxAppDomain(permissions);

Dim permissions As New PermissionSet(PermissionState.None)
permissions.AddPermission(New FileIOPermission(PermissionState.Unrestricted))
permissions.AddPermission(New SecurityPermission(SecurityPermissionFlag.Execution))

ReportViewer1.LocalReport.SetBasePermissionForSandboxAppDomain(permissions)
