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

问题描述

我有一个结构xyz"，其中包含 3 个字符串对象."foo" "bar" 和 "abc" 我想遍历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

伪:

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

如果这只是一次性的事情，您可能会更轻松地使用字典，但如果您愿意，可以使用反射来做到这一点保持结构.

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.

这个小代码片段将在 StringBuilder 中为您列出每个结构成员.

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
