Creating a new record with giving record type

I want to create a new record on click of button by giving its record type.

please find the code below

public pageReference Test()
    {
       RecordType rt =[SELECT ID, name FROM RecordType WHERE SObjectType = 'App__c' and name='Test_Contact'];

      this.ap.Client__c = account.Id;
      this.ap.RecordTypeId =rt.Id;
      insert (this.ap);


        pageReference pageRef = new pageReference('/oaoa/TestForm');
        pageRef.setRedirect(true);
        pageRef.getParameters().put('id',ap.id);

       return pageRef;

    }

I am getting error as List has no rows for assignment to SObject
Rt is not returning any value

Method 1

Well, maybe the query really doesn’t return anything?

What does SELECT ID, name FROM RecordType WHERE SObjectType = 'App__c' return?

Is the name really ‘Test_Contact’? Look at your config and try with ‘Test Contact’. Even better – query by API name of the rec. type (less likely to be translated to French for example ;)):

WHERE SObjectType = 'App__c' and DeveloperName = 'Test_Contact'
