| Item | Gets the specified QualifierData from the QualifierDataCollection. |
| SyncRoot | Gets the object to be used for synchronization. |
| Name | Description | |
|---|---|---|
| Add(String, Object) | Adds a QualifierData to the QualifierDataCollection. This overload specifies the qualifier name and value. |
| Add(String, Object, Boolean, Boolean, Boolean, Boolean) | Adds a QualifierData to the QualifierDataCollection. This overload specifies all property values for a QualifierData. |
| CopyTo(Array, Int32) | Copies the QualifierDataCollection into an array. |
| CopyTo(QualifierData[], Int32) | Copies the QualifierDataCollection into a specialized QualifierData array. |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetEnumerator | Returns an enumerator for the QualifierDataCollection. This method is strongly typed. |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |

| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |

| AsParallel | Enables parallelization of a query. (Defined by ParallelEnumerable.) |
| AsQueryable | Converts an IEnumerable to an IQueryable. (Defined by Queryable.) |
| Cast<TResult> | Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.) |
| OfType<TResult> | Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.) |
| Name | Description | |
