FileTypeSet Class

Represents a set of file patterns.

When combining patterns in string representation (e.g. when setting in markup), they should be separated by vertical bar (|).

In a pattern, you can use these wildcards:

* matches zero or more characters.
? matches exactly one character.

Some pattern examples:

*.* matches files with any extension (does not match files without an extension)
*.jpg matches files only with jpg extension
picture*.jpg matches files only with jpg extension and which names start with 'picture'
picture.* matches files with any extension and which names start with 'picture'
picture matches files with no extension and which names are exactly 'picture'
*.jp* matches files like 'picture.jpg', 'otherpicture.jpe', 'somepicture.jpeg' etc.
*.jp? matches files like 'picture.jpg', 'otherpicture.jpe' etc.
picture?.jpg matches files like 'picture1.jpg', 'picture2.jpg', 'pictures.jpg' etc.

Example

Setting access control file types in code:

//allow only *.jpg and *.gif
accessControl.AllowedFileTypes = "*.jpg|*.gif";
//or
accessControl.AllowedFileTypes = FileTypeSet.Parse("*.jpg|*.gif");
//or
accessControl.AllowedFileTypes = new FileTypeSet
{
    "*.jpg",
    "*.gif"
};

//allow all except *.exe and *.dll
accessControl.DeniedFileTypes = "*.exe|*.dll";
//or
accessControl.DeniedFileTypes = FileTypeSet.Parse("*.exe|*.dll");
//or
accessControl.DeniedFileTypes = new FileTypeSet
{
    "*.exe",
    "*.dll"
};

'allow only *.jpg and *.gif
accessControl.AllowedFileTypes = "*.jpg|*.gif"
'or
accessControl.AllowedFileTypes = FileTypeSet.Parse("*.jpg|*.gif")
'or
accessControl.AllowedFileTypes = New FileTypeSet() From {
    "*.jpg",
    "*.gif"
}

'allow all except *.exe and *.dll
accessControl.DeniedFileTypes = "*.exe|*.dll"
'or
accessControl.DeniedFileTypes = FileTypeSet.Parse("*.exe|*.dll")
'or
accessControl.DeniedFileTypes = New FileTypeSet() From {
    "*.exe",
    "*.dll"
}

Setting access control file types in ASPX markup:

ASPX

<%-- allow only *.jpg and *.gif --%>
<GleamTech:FileManagerAccessControl 
    Path="\" 
    AllowedPermissions="Full" 
    AllowedFileTypes="*.jpg|*.gif" /> 

<%-- allow all except *.exe and *.dll --%>
<GleamTech:FileManagerAccessControl 
    Path="\" 
    AllowedPermissions="Full" 
    DeniedFileTypes="*.exe|*.dll" />

Constructors

FileTypeSet	Initializes a new instance of the FileTypeSet class.
FileTypeSet(IEnumerableString)	Initializes a new instance of the FileTypeSet class.

Properties

Comparer	Gets the IEqualityComparerT object that is used to determine equality for the values in the set. (Inherited from HashSetString)
Count	Gets the number of elements that are contained in a set. (Inherited from HashSetString)

Methods

Add	Adds the specified element to a set. (Inherited from HashSetString)
Clear	Removes all elements from a HashSetT object. (Inherited from HashSetString)
Contains	Determines whether a HashSetT object contains the specified element. (Inherited from HashSetString)
CopyTo(T)	Copies the elements of a HashSetT object to an array. (Inherited from HashSetString)
CopyTo(T, Int32)	Copies the elements of a HashSetT object to an array, starting at the specified array index. (Inherited from HashSetString)
CopyTo(T, Int32, Int32)	Copies the specified number of elements of a HashSetT object to an array, starting at the specified array index. (Inherited from HashSetString)
ExceptWith	Removes all elements in the specified collection from the current HashSetT object. (Inherited from HashSetString)
GetEnumerator	Returns an enumerator that iterates through a HashSetT object. (Inherited from HashSetString)
GetObjectData	Implements the ISerializable interface and returns the data needed to serialize a HashSetT object. (Inherited from HashSetString)
IntersectWith	Modifies the current HashSetT object to contain only elements that are present in that object and in the specified collection. (Inherited from HashSetString)
IsProperSubsetOf	Determines whether a HashSetT object is a proper subset of the specified collection. (Inherited from HashSetString)
IsProperSupersetOf	Determines whether a HashSetT object is a proper superset of the specified collection. (Inherited from HashSetString)
IsSubsetOf	Determines whether a HashSetT object is a subset of the specified collection. (Inherited from HashSetString)
IsSupersetOf	Determines whether a HashSetT object is a superset of the specified collection. (Inherited from HashSetString)
OnDeserialization	Implements the ISerializable interface and raises the deserialization event when the deserialization is complete. (Inherited from HashSetString)
Overlaps	Determines whether the current HashSetT object and a specified collection share common elements. (Inherited from HashSetString)
Parse	Converts the string representation of a set of file patterns to its FileTypeSet equivalent.
Remove	Removes the specified element from a HashSetT object. (Inherited from HashSetString)
RemoveWhere	Removes all elements that match the conditions defined by the specified predicate from a HashSetT collection. (Inherited from HashSetString)
SetEquals	Determines whether a HashSetT object and the specified collection contain the same elements. (Inherited from HashSetString)
SymmetricExceptWith	Modifies the current HashSetT object to contain only elements that are present either in that object or in the specified collection, but not both. (Inherited from HashSetString)
ToRegex	Converts the current set of file patterns to its Regex equivalent.
ToString	Converts the current set of file patterns to a string representation with default separator '\|'. (Overrides ObjectToString)
ToString(String)	Converts the current set of file patterns to a string representation with a custom separator.
TrimExcess	Sets the capacity of a HashSetT object to the actual number of elements it contains, rounded up to a nearby, implementation-specific value. (Inherited from HashSetString)
TryGetValue	Searches the set for a given value and returns the equal value it finds, if any. (Inherited from HashSetString)
UnionWith	Modifies the current HashSetT object to contain all elements that are present in itself, the specified collection, or both. (Inherited from HashSetString)

Operators

(String to FileTypeSet)

Converts the string representation of a set of file patterns to its FileTypeSet equivalent.
