如何获得vbfixedstring（5）中定义的结构变量的大小？ [英] How can I get a size of the structure variable defined in vbfixedstring(5)?

问题描述

您好



我正在处理从vb6到vb.net的转换项目。



旧项目包含声明字符串大小的VBFixedString，它们从结构中检索大小。但是在将项目转换为VB.Net之后，代码已经像下面显示的代码一样进行迁移。



私有结构StructureName

Hi

I am working on converted project from vb6 to vb.net.

The old project contains the VBFixedString of declaring a size of the string and they retrieving the size from the structure.But After converted project to VB.Net the code has been migrated like the code shown below.

Private Structure StructureName

<VBFixedString(2), System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst:=2)> Public xxx() As Char

结束结构



但我无法检索大小变量



我尝试过：

End Structure

But I can't able to retrieve the size of the variable

What I have tried:

I tried marshal,but it gives the total size of the structure alone.

Marshal.SizeOf(X)

Can someone give me a solution to retrieve the size of the particular variable inside the structure which is using VBFixedString or else give me some suggestions to declare the variable by defining size inside the structure to retrieve the size?

Thanks in Advance.

推荐答案

看看这些;



[ ^ ]



sizeof vs Marshal.SizeOf [ ^ ]

Look at these;

Marshal variable length array of structs from C to VB.NET[^]

sizeof vs Marshal.SizeOf[^]
