Examples

The following code example demonstrates the use of the MustRunInClientContextAttribute type.

using System;
using System.EnterpriseServices;
using System.Reflection;

// References:
// System.EnterpriseServices

[MustRunInClientContext]
public class MustRunInClientContextAttribute_Ctor : ServicedComponent
{
}

[MustRunInClientContext(false)]
public class MustRunInClientContextAttribute_Ctor_Bool : ServicedComponent
{
}

[MustRunInClientContext(false)]
public class MustRunInClientContextAttribute_Value : ServicedComponent
{
    public void ValueExample()
    {
        // Get the MustRunInClientContextAttribute applied to the class.
        MustRunInClientContextAttribute attribute =
            (MustRunInClientContextAttribute)Attribute.GetCustomAttribute(
            this.GetType(),
            typeof(MustRunInClientContextAttribute),
            false);

        // Display the value of the attribute's Value property.
        Console.WriteLine("MustRunInClientContextAttribute.Value: {0}",
            attribute.Value);
    }
}

Remarks

If the context attributes of the attributed object conflict with those of the context of the creator, a System.Runtime.InteropServices.COMException is thrown when an attempt is made to create the object.

Constructors

MustRunInClientContextAttribute()	Initializes a new instance of the MustRunInClientContextAttribute class, requiring creation of the object in the context of the creator.
MustRunInClientContextAttribute(Boolean)	Initializes a new instance of the MustRunInClientContextAttribute class, optionally not creating the object in the context of the creator.

Properties

TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
Value	Gets a value that indicates whether the attributed object is to be created in the context of the creator.

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
