Question

我如何在VB.NET中执行以下操作

List<T[]> result = new List<T[]>();

// single combination
if (k == 0)
{
   result.Add(new T[0]); // T is function type argument of generic function

如何在VB.NET中编写上面的最后一行？

我试过了：

result.Add(New T(0)) 'doesn't work!

Answer 1

应该是：

result.Add(New T(0) {})

Answer 2

我尝试了以下内容：

    Dim A(0) As T                   ' Length = 1
    Dim B As T() = New T(0) {}      ' Length = 1
    Dim C As T() = New T() {}       ' Length = 0
    Dim D As T() = New T(-1) {}     ' Length = 0
    Dim E(-1) As T                  ' Length = 0
    Dim F As T() = Array.CreateInstance(GetType(T), 0)  ' Length = 0

所以我建议第三个选项是最干净的。
