使用Int32.Parse():这个方法与Convert.ToInt32()类似,但它在某些情况下可能提供更详细的异常信息,并且对于某些特定场景(如使用NumberStyles)提供了更多控制。 vb.net Dim str As String = "456" Try Dim number As Integer = Int32.Parse(str) Console.WriteLine(
Dim s As String = "12"以下三种写法都可以：Dim n As Integer = CType(s, Integer)Dim m As Integer = Convert.ToInt32(s)Dim o As Integer = Integer.Parse(s)VB.NET入门之数据类型转换 cbool将字符串或者数值转换成布尔型函数；cobj将内容转换成object；cbyte将字符串或者数值转换成byte型...
