MSMQ cannot delete or purge a queue

I think there is rights issue. You are not able to give rights then do following step for forcefully delete queue. Stop following services Message Queuing Triggers, Net.Msmq Listener Adapter Message Queuing. Go to C:\Windows\System32\msmq\storage\lqs Now open file in notepad or notepad++ and see the name of queue at QueueName=\private$\YourQueueName Before delete file backup the file. Now delete that file. Don't delete other file which does not have your queue name. Do these things as your own risk. Now start following services Message Queuing Triggers, Net.Msmq Listener Adapter Message Queuing. This trick work for me...

I made on extension helper to get display name or description  of Enum.


Usage:

    Sun,
    [Display(Name = "Monday")]
    Mon,
    [Display(Name = "Tuesday")]

No set method for property in WCF service

Problem:

I have some class that I'm passing as a result of a service method, and that class has a get-only property:
 

public string PropertyName
{
    get
    {
        return "Some Value";
    }    
}

 I'm getting an exception on service side "No set method for property"

Solution:

Remember that WCF needs to create an instance of the object from its serialized representation (often XML) and if the property has no setter it cannot assign a value. Objects are not transferred between the client and the server but only serialized representations, so the object needs to be reconstructed at each end.

Make setter property private. So, client can never see the set method on your property acting much like a read only property. 

public string PropertyName
{
    get
    {
        return "Some Value";
    }
    private set
    { }
}

C# datetime formatting separators issue

Problem:

Console.WriteLine(DateTime.Now.ToString("MM/dd/yyyy"));  

Output:

08-28-2013 

Expected output: 

08/28/2013

Solution:

Console.WriteLine(DateTime.Now.ToString("MM/dd/yyyy", CultureInfo.InvariantCulture));

Reason,

If a CultureInfo is not specified, the current culture will be used.

If this is a culture that doesn't use slashes as separators in dates and 

the format string specifies the date separator to be a /, that is replaced 

by whatever the actual culture date separator is –

WCF: The maximum array length quota (16384) has been exceeded while reading XML data

Error:

"The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader."

Solution:

Try to change config file:

Add <readerQuotas> and set maxArrayLength="2147483647"

<binding name="WSHttpBinding_IBackup"
         closeTimeout="1:00:00"
         maxBufferPoolSize="2147483647"
         maxBufferSize="2147483647"
         maxReceivedMessageSize="2147483647"
         openTimeout="1:00:00"
         receiveTimeout="1:00:00"
         sendTimeout="1:00:00"
         transferMode="Streamed">
 
  <readerQuotas
    maxArrayLength="2147483647"
    maxBytesPerRead="2147483647"
    maxDepth="2147483647"
    maxNameTableCharCount="2147483647"
    maxStringContentLength="2147483647" />
 
  <!--if any issue then try this one-->
  <!--<textMessageEncoding messageVersion="Soap11" 
                       maxReadPoolSize="2147483647" 
                       maxWritePoolSize="2147483647">
    <readerQuotas
      maxArrayLength="2147483647"
      maxBytesPerRead="2147483647"
      maxDepth="2147483647"
      maxNameTableCharCount="2147483647"
      maxStringContentLength="2147483647" />
  </textMessageEncoding>-->
 
</binding>

If you have same issue then try following solution.

Reason:-

• My service is simply ignoring my binding “basicHttp_ServiceName” and it’s always taking default binding
• Reason is
  
  • My configuration service name does not match with service name in Service Host
  • The name I given is "ServiceName" where it has to be "XYZ.ServiceName"
  • E.g.
    

    <%@ ServiceHost Language="C#" 
                    Debug="true" 
                    Service="XYZ.ServiceName" 
                    CodeBehind="ServiceName.svc.cs" %>
    
    

Fix :-

• Right click your “.svc” file and choose “View Markup”
• Copy the Service name and paste it in your service name
• Now my Service configuration looks below
• E.g
  

   <services>
      <service name="XYZ.ServiceName">
   
      </service>
    </services>
