我正在尝试将值设置为
For i = gSources.GetLowerBound(0) To gSources.GetUpperBound(0) Step 1
gSources(i).chan_nr = i
'gSources is 0 based ?
If gSources.GetLowerBound(0) = 0 Then
k = i + 1
Else
k = i
End If
Dim hehe As Integer = gSources.Count
For j = gNoiseBands.GetLowerBound(0) To gNoiseBands.GetUpperBound(0) Step 1
'ab 17.1.2012: gNrSources sets nr of available outputs
If k <= gNrSources Then
gSources(i).OnOff(j) = eSourceMode.EIN
Else
gSources(i).OnOff(j) = eSourceMode.AUS
End If
Next j
Next i
结果是异常
System.NullReferenceException 发生
你调用的对象是空的。
我需要这个,因为我有 .ini 文件和这些值:
"gSources0",1,0,1,1,1,1,1
"gSources1",1,1,1,1,1,1,1
"gSources2",1,1,1,1,1,1,1
"gSources3",1,1,1,1,1,1,1
的结果应该是一个例子:
gSources(0).OnOff(0) = 1 , gSources(0).OnOff(1) = 0
