使用字符串作为vb函数

Question

我有一个字符串替换，但我想用它作为一个真正的vb.net函数，有可能这样做吗？例如：

dim str as string = "my task"
dim func as string = "Replace(str, " ", "-")"
dim result as string = 'here I must to use func string to have into result "my-task"

请帮助我

Answer 1

这是怎么做的：

Dim inputString As String = "my task"
Dim methodName As String = "Replace"
Dim arguments = New String() {" ", "-"}

Dim result = CallByName(inputString, methodName, CallType.Method, arguments)

这相当于：

Dim inputString As String = "my task"
Dim result = inputString.Replace(" ", "-")

虽然值得注意：很可能有更好的方法来组织代码。从字符串执行函数有多个缺点，您可能希望避免这些。
