Delay

Public Sub Delay(ByRef HowLong As Double) On Error Resume Next Dim throughTime As DateTime Dim Dnow As DateTime = DateTime.与"Delay(ref double HowLong)"最匹配的重载方法具有一些无效参数错误2.错误1与"Delay(ref double HowLong)"最匹配的重载方法具有一些无效参数错误2.Delay(int HowLong)函数，而你仅仅定义了Delay(ref double HowLong)函数。方法一、如8620(tuenhai)所说，更改public void Delay(ref double HowLong)， 定义为public void Delay(double HowLong)Delay(ref HowLong );
