AsBaseType``2(
``0)DirectCast(obj, T). 这个函数主要是为了解决Class类型之间的继承类型的转换，例如子类型向基础类型转换
Remarks
可能会和向量的As类型转换有冲突
Type Parameters
| Name | Description |
|---|---|
T |
Parameters
| Name | Type | Description |
|---|---|---|
obj | ``0 | - |
As``2(
IEnumerable(Of ``0))Cast array type
Type Parameters
| Name | Description |
|---|---|
T | |
TOut |
Parameters
| Name | Type | Description |
|---|---|---|
list | IEnumerable(Of ``0) | 在这里使用向量而非使用通用接口是因为和单个元素的As转换有冲突 |
RegexParseDouble(
