How to detect if DXCore is loaded from another add-in
January 17th, 2011
Note, this article has been moved to the official DevExpress Support Center site. Please refer to the moved article as it might have further updates or additional comments. Thank you.
Here is a sample code illustrating how to detect if the DXCore is installed and loaded from another add-in (without static dependencies on the DXCore assemblies) using reflection. This could be helpful if your add-in functionality somehow intersects with the DXCore’s.
From inside a usual DXCore plug-in, you can detect if the DXCore is loaded by calling the “CodeRush.IsLoaded” property. In case you are not going to reference the DXCore assemblies inside your add-in, this sample might help.
CSharp code:
bool DXCoreIsLoaded
{
get
{
try
{
const string CodeRushObjectTypeName = "DevExpress.CodeRush.Core.CodeRush";
const string IsLoadedPropertyName = "IsLoaded";
Assembly DXCoreMainAssembly = GetDXCoreMainAssembly();
if (DXCoreMainAssembly == null)
return false;
Type CodeRushObjectType = DXCoreMainAssembly.GetType(CodeRushObjectTypeName);
if (CodeRushObjectType == null)
return false;
PropertyInfo IsLoadedProperty = CodeRushObjectType.GetProperty(IsLoadedPropertyName, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Static);
if (IsLoadedProperty == null)
return false;
object IsLoadedValue = IsLoadedProperty.GetValue(null, null);
if (IsLoadedValue == null)
return false;
return (bool)IsLoadedValue;
}
catch
{
return false;
}
}
}
Assembly GetDXCoreMainAssembly()
{
const string DXCoreMainAssemblyName = "DevExpress.CodeRush.Core";
Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();
foreach (Assembly assembly in assemblies)
if (assembly.FullName.StartsWith(DXCoreMainAssemblyName))
return assembly;
return null;
}
Visual Basic code:
ReadOnly Property DXCoreIsLoaded() As Boolean
Get
Try
Const CodeRushObjectTypeName As String = "DevExpress.CodeRush.Core.CodeRush"
Const IsLoadedPropertyName As String = "IsLoaded"
Dim DXCoreMainAssembly As Assembly = GetDXCoreMainAssembly()
If DXCoreMainAssembly Is Nothing Then
Return False
End If
Dim CodeRushObjectType As Type = DXCoreMainAssembly.GetType(CodeRushObjectTypeName)
If CodeRushObjectType Is Nothing Then
Return False
End If
Dim IsLoadedProperty As PropertyInfo = CodeRushObjectType.GetProperty(IsLoadedPropertyName, BindingFlags.IgnoreCase Or BindingFlags.Public Or BindingFlags.Static)
If IsLoadedProperty Is Nothing Then
Return False
End If
Dim IsLoadedValue As Object = IsLoadedProperty.GetValue(Nothing, Nothing)
If IsLoadedValue Is Nothing Then
Return False
End If
Return CType(IsLoadedValue, Boolean)
Catch
Return False
End Try
End Get
End Property
Function GetDXCoreMainAssembly() As Assembly
Const DXCoreMainAssemblyName As String = "DevExpress.CodeRush.Core"
Dim assemblies As Assembly() = AppDomain.CurrentDomain.GetAssemblies()
For Each assembly As Assembly In assemblies
If assembly.FullName.StartsWith(DXCoreMainAssemblyName) Then
Return assembly
End If
Next
Return Nothing
End Function
