![]() | Contains(String) | Determines whether the specified string is in the StringCollection. |
![]() | CopyTo(String[], Int32) | Copies the entire StringCollection values to a one-dimensional array of strings, starting at the specified index of the target 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 a StringEnumerator that iterates through the StringCollection. |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | IndexOf(String) | Searches for the specified string and returns the zero-based index of the first occurrence within the StringCollection. |
![]() | Insert(Int32, String) | Inserts a string into the StringCollection at the specified index. |
![]() | MemberwiseClone() | |
![]() | Remove(String) | Removes the first occurrence of a specific string from the StringCollection. |
![]() | RemoveAt(Int32) | Removes the string at the specified index of the StringCollection. |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | ICollection.CopyTo(Array, Int32) | Copies the entire StringCollection to a compatible one-dimensional Array, starting at the specified index of the target array. |
![]() ![]() | IEnumerable.GetEnumerator() | Returns a IEnumerator that iterates through the StringCollection. |
![]() ![]() | IList.Add(Object) | Adds an object to the end of the StringCollection. |
![]() ![]() | IList.Contains(Object) | Determines whether an element is in the StringCollection. |
![]() ![]() | IList.IndexOf(Object) | Searches for the specified Object and returns the zero-based index of the first occurrence within the entire StringCollection. |
![]() ![]() | IList.Insert(Int32, Object) | Inserts an element into the StringCollection at the specified index. |
![]() ![]() | IList.Remove(Object) | Removes the first occurrence of a specific object from the StringCollection. |
![]() ![]() | IList.IsFixedSize | Gets a value indicating whether the StringCollection object has a fixed size. |
![]() ![]() | IList.IsReadOnly | Gets a value indicating whether the StringCollection object is read-only. |
![]() ![]() | IList.Item(Int32) | Gets or sets the element at the specified index. |
| Name | Description | |
|---|---|---|
![]() | AsParallel() | Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.) |
![]() | AsQueryable() | Overloaded. 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.) |
StringCollection accepts null as a valid value and allows duplicate elements.
String comparisons are case-sensitive.
Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
This implementation does not provide a synchronized (thread safe) wrapper for a StringCollection, but derived classes can create their own synchronized versions of the StringCollection using the SyncRoot property.
Enumerating through a collection is intrinsically not a thread safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.
