vb.net结构体数组 vb定义结构体类型

VB.net中怎么定义初始化一个结构体数组struct T_ChildStruct
{
int nChildData;
string strChildData;
T_ChildStruct()
{
nChildData = https://www.04ip.com/post/0;
strChildDatahttps://www.04ip.com/post/= "";// string可以不用写初始化,本身构造中就有
}
};
struct T_FatherStruct
{
int nFatherData;
string strFatherData;
T_ChildStruct arrChild[10];
T_FatherStruct()
{
nFatherData = https://www.04ip.com/post/0;
strFatherDatahttps://www.04ip.com/post/= "";
}
};
vb.net 如何在结构体内设定定长数组结构体无法初始化值 , 你可以用类实现,或者写一个构造函数,把值传进去 。
Public Structure wheelmodel
Public ID As Short
Public swapway() As Short
Public start As Short
Public Sub New(ByVal Size As UShort) 'Size就是传入的数组的大小
swapway = New Short(Size) {}
End Sub
End Structure
调用的时候:
Dim x As wheelmodel = New wheelmodel(10)
VB.net的结构体怎么一次性赋值,结构数组怎么一次性赋值?把“...”替换成你要初始化的数据 。一个简单的例子:Dim a(3) As Integer = { 0, 1, 2 }**修改**既然有界数组不能初始化,就还缺(?。┙缡槭允月铮?Dim a() As Integer = { 0, 1, 2 }类型不匹配的错误估计是你的结构体缺少构造函数造成的 。在你的quality_i结构体定义里面加一个构造函数 , 如下所示Public Structure quality_iPublic nub As IntegerPublic nae As StringPublic Sub New(ub As Integer, ae As String)nub = ubnae = aeEnd SubEnd Structure然后以如下方式初始化:Dim k() As quality_i = {
VB.NET 结构体数组定义 始终显示“未将对象引用设置到对象的实例”你没有将数组定义为一个新的实例:
dim
j
as
Integer
dim
a(100)
as
new
Phvalue
for
j=0
to
501
