VB.NET迭代结构的对象 [英] VB.NET Iterating through objects of a structure

问题描述

我有一个结构xyz，里面有3个字符串对象。 foobar和abc我想迭代结构并比较对象的名称。

I have a structure "xyz" with 3 string objects in it. "foo" "bar" and "abc" I want to iterate through the structure and compare the names of the objects.

Structure xyz
    dim foo as string
    dim bar as string
    dim abc as string
End Structure

Pseudo：

For each x as object in xyz 
    if x.Name = "foo" then
        'bang
    end if
End each

这可能吗？

推荐答案

如果这只是一次性事情，你可能会有更轻松的时间改为使用Dictionary，但如果你想保留结构，你可以用Reflection做到这一点。

If this is just a one time thing you're probably going to have an easier time using a Dictionary instead, but you could do this with Reflection if you prefer to keep the structure.

这个小代码片段将为你列出每个结构成员 StringBuilder 。

This little code snippet will list out each structure member for you in a StringBuilder.

Dim sbOutput As New System.Text.StringBuilder
Dim t As Type = GetType(xyz)
For Each p As System.Reflection.FieldInfo In t.GetFields()
  sbOutput.AppendLine(p.Name)
Next
