TopologicalSort<TNode>(IEnumerable<TNode>, Func<TNode, IEnumerable<TNode>>)

Improve this Doc View Source

Sorts a given dependency graph using a direct toposort, reporting possible cyclic dependencies.

Declaration
public static IEnumerable<TNode> TopologicalSort<TNode>(IEnumerable<TNode> nodes, Func<TNode, IEnumerable<TNode>> dependencySelector)
Parameters
Type Name Description
System.Collections.Generic.IEnumerable<TNode> nodes

Nodes to sort
System.Func<TNode, System.Collections.Generic.IEnumerable<TNode>> dependencySelector

Function that maps a node to a collection of its dependencies.
Returns
Type Description
System.Collections.Generic.IEnumerable<TNode>

Collection of nodes sorted in the order of least dependencies to the most.
Type Parameters
Name Description

TryOpenFileStream(String, FileMode, out FileStream, FileAccess, FileShare)

Improve this Doc View Source

Tries to create a file with the given name

Declaration
public static bool TryOpenFileStream(string path, FileMode mode, out FileStream fileStream, FileAccess access = FileAccess.ReadWrite, FileShare share = FileShare.Read)
Parameters
Type Name Description

Path of the file to create
System.IO.FileMode mode

File open mode
System.IO.FileStream fileStream

TryParseAssemblyName(String, out AssemblyName)

Improve this Doc View Source

Try to parse given string as an assembly name

Declaration
public static bool TryParseAssemblyName(string fullName, out AssemblyName assemblyName)
Parameters
Type Name Description
System.String fullName
