Methods
public
void
CreateAsSymbolicLink(string pathToTarget)
pathToTarget
The path of the symbolic link target.
Creates a symbolic link located in <see cref="P:System.IO.FileSystemInfo.FullName" /> that points to the specified <paramref name="pathToTarget" /> .
public
void
Delete()
Deletes a file or directory.
public
void
GetObjectData(Runtime.Serialization.SerializationInfo info,
Runtime.Serialization.StreamingContext context)
info
The <see cref="T:System.Runtime.Serialization.SerializationInfo" /> that holds the serialized object data about the exception being thrown.
context
The <see cref="T:System.Runtime.Serialization.StreamingContext" /> that contains contextual information about the source or destination.
Sets the <see cref="T:System.Runtime.Serialization.SerializationInfo" /> object with the file name and additional exception information.
public
void
Refresh()
Refreshes the state of the object.
public
FileSystemInfo
ResolveLinkTarget(bool returnFinalTarget)
returnFinalTarget
<see langword="true" /> to follow links to the final target; <see langword="false" /> to return the immediate next link.
Returns A <see cref="T:System.IO.FileSystemInfo" /> instance if the link exists, independently if the target exists or not; <see langword="null" /> if this file or directory is not a link.
Gets the target of the specified link.
public
string
ToString() Returns A string with the original path.
Returns the original path. Use the <see cref="P:System.IO.FileSystemInfo.FullName" /> or <see cref="P:System.IO.FileSystemInfo.Name" /> properties for the full path or file/directory name.
public
object
GetLifetimeService()
Inherited from MarshalByRefObject
Returns An object of type <see cref="T:System.Runtime.Remoting.Lifetime.ILease" /> used to control the lifetime policy for this instance.
Retrieves the current lifetime service object that controls the lifetime policy for this instance.
public
object
InitializeLifetimeService()
Inherited from MarshalByRefObject
Returns An object of type <see cref="T:System.Runtime.Remoting.Lifetime.ILease" /> used to control the lifetime policy for this instance. This is the current lifetime service object for this instance if one exists; otherwise, a new lifetime service object initialized to the value of the <see cref="P:System.Runtime.Remoting.Lifetime.LifetimeServices.LeaseManagerPollTime" /> property.
Obtains a lifetime service object to control the lifetime policy for this instance.
protected
MarshalByRefObject
MemberwiseClone(bool cloneIdentity)
Inherited from MarshalByRefObject
cloneIdentity
<see langword="false" /> to delete the current <see cref="T:System.MarshalByRefObject" /> object's identity, which will cause the object to be assigned a new identity when it is marshaled across a remoting boundary. A value of <see langword="false" /> is usually appropriate. <see langword="true" /> to copy the current <see cref="T:System.MarshalByRefObject" /> object's identity to its clone, which will cause remoting client calls to be routed to the remote server object.
Returns A shallow copy of the current <see cref="T:System.MarshalByRefObject" /> object.
Creates a shallow copy of the current <see cref="T:System.MarshalByRefObject" /> object.
public
bool
Equals(object obj)
Inherited from object
obj
The object to compare with the current object.
Returns <see langword="true" /> if the specified object is equal to the current object; otherwise, <see langword="false" /> .
Determines whether the specified object is equal to the current object.
protected
void
Finalize()
Inherited from object
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
public
int
GetHashCode()
Inherited from object
Returns A hash code for the current object.
Serves as the default hash function.
public
Type
GetType()
Inherited from object
Returns The exact runtime type of the current instance.
Gets the <see cref="T:System.Type" /> of the current instance.
protected
object
MemberwiseClone()
Inherited from object
Returns A shallow copy of the current <see cref="T:System.Object" /> .
Creates a shallow copy of the current <see cref="T:System.Object" /> .
