现在发现,熟悉NET提供的静态方法是很重要的,不熟悉不熟知,会走好多弯路.
当然,走弯路也不是坏事,只是时间有限,经验和技能不能在弯路中积累.
下面的功能是看看指定类所在的程序集究竟公布了哪些静态方法.
Imports System.Reflection
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim mNode1 As TreeNode = AssemblyStaticMethodNode(GetType(Object))
Dim mNode2 As TreeNode = AssemblyStaticMethodNode(GetType(Microsoft.VisualBasic.Strings))
With Me.TreeView1
.BeginUpdate()
.Nodes.Clear()
.Nodes.AddRange(New TreeNode() {mNode1, mNode2})
.Sort()
.EndUpdate()
End With
End Sub
Public Function AssemblyStaticMethodNode(ByVal t As Type) As TreeNode
Dim mAssembly As Assembly = Assembly.GetAssembly(t)
Dim mRootNode As New TreeNode(mAssembly.GetName.Name)
Dim mSecondNode As TreeNode = Nothing
Dim mCurrentNode As TreeNode = Nothing
Dim mCurrentTypeChanged As Boolean = False
Dim mBinding As BindingFlags = BindingFlags.Public & BindingFlags.Static
For Each mModule As [Module] In mAssembly.GetModules
mSecondNode = mRootNode.Nodes.Add(mModule.ScopeName)
For Each mType As Type In mModule.GetTypes
If mType.IsClass Then
mCurrentTypeChanged = True
For Each mMethod As MethodInfo In mType.GetMethods(mBinding)
If mCurrentTypeChanged Then
mCurrentNode = mSecondNode.Nodes.Add(mType.FullName)
mCurrentTypeChanged = False
End If
mCurrentNode.Nodes.Add(mMethod.ToString)
Next
End If
Next
Next
Return mRootNode
End Function
End Class
