Methods
DirectoryExists(String)
Gets a value that indicates whether a directory exists in the virtual file system.
Declaration
public override bool DirectoryExists(string virtualDir)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | virtualDir | The virtual path. |
Returns
| Type | Description |
|---|---|
| System.Boolean | true if the directory exists in the virtual file system, otherwise false. |
FileExists(String)
Gets a value that indicates whether a file exists in the virtual file system.

public override bool FileExists(string virtualPath)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | virtualPath | The virtual path. |
Returns
| Type | Description |
|---|---|
| System.Boolean | true if the file exists in the virtual file system, otherwise false. |
GetCacheDependency(String, IEnumerable, DateTime)
Creates a cache dependency based on the specified virtual paths.
Declaration
public override CacheDependency GetCacheDependency(string virtualPath, IEnumerable virtualPathDependencies, DateTime utcStart)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | virtualPath | The path to the primary virtual resource. |
| System.Collections.IEnumerable | virtualPathDependencies | An array of paths to other resources required by the primary virtual resource. |
| System.DateTime | utcStart | The UTC time at which the virtual resources were read. |
Returns
| Type | Description |
|---|---|
| System.Web.Caching.CacheDependency | A System.Web.Caching.CacheDependency object for the specified virtual resources. |
Remarks
virtualPathDependencies has to be an System.Collections.IEnumerable of System.String. All the elements that are not strings will be ignored. No exception will be thrown.
GetDirectory(String)
Gets a directory from the virtual filesystem.
Declaration
public override VirtualDirectory GetDirectory(string virtualDir)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | virtualDir | The virtual path. |
Returns
| Type | Description |
|---|---|
| System.Web.Hosting.VirtualDirectory | A System.Web.Hosting.VirtualDirectory object representing the virtual path. |
Remarks
If the specified virtual path is not handled by the current virtual path provider the next provider in the provider chain is queried.
GetFile(String)
Gets a file from the virtual filesystem.
Declaration
public override VirtualFile GetFile(string virtualPath)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | virtualPath | The virtual path. |
Returns
| Type | Description |
|---|---|
| System.Web.Hosting.VirtualFile | A System.Web.Hosting.VirtualFile object representing the virtual path. |
Remarks
If the specified virtual path is not handled by the current virtual path provider the next provider in the provider chain is queried.
GetFileHash(String, IEnumerable)

Declaration
public override string GetFileHash(string virtualPath, IEnumerable virtualPathDependencies)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | virtualPath | The path to the primary virtual resource. |
| System.Collections.IEnumerable | virtualPathDependencies | An array of paths to other virtual resources required by the primary virtual resource. |
Returns
| Type | Description |
|---|---|
| System.String | A hash of the files specified in the virtual path dependencies. |
MapPathInternal(DirectoryInfo, String)
Maps a virtual path to it's corresponding physical path, given a physical path base.
Declaration
protected string MapPathInternal(DirectoryInfo physicalPathBase, string virtualPath)Parameters
| Type | Name | Description |
|---|---|---|
| System.IO.DirectoryInfo | physicalPathBase | The base physical path. |
| System.String | virtualPath | The virtual path. |
Returns
| Type | Description |
|---|---|
| System.String | A physical path |
Remarks
The implementation expects that virtualPath is a absoulte virtualPath starting with the path this provider instance is registered with. Validation can be performed by TryGetHandledAbsolutePath(String, out String)
MapVirtualPathToLocalPath(String, out String)
Maps a virtual (relative) path to an local absolute path
Declaration
public bool MapVirtualPathToLocalPath(string virtualPath, out string outLocalPath)Parameters

Returns
| Type | Description |
|---|---|
| System.Boolean | True if virtual path was mapped successfully to an absolute path within the namespace of this provider, false otherwise |
Remarks
Note that this function does not check if the file actually exists, it only cares about path mapping
TryGetHandledAbsolutePath(String, out String)
