我正在尝试在检查可视源安全文件之前将一个LABEL（不是注释，它可以）应用于VSSItem。
我测试了许多参数，检查了文件类型等。
我可以正确地检查文件中没有问题，并添加注释，这是checkin方法的属性。我无法做的是添加标签....
vssItem.Label(msg1, msg2)
msg1和msg2只是for stmt。
上面定义的字符串For Each vssItem As IVSSItem In vssFolder.Items(False)
Console.Write(" {0}", vssItem.Name)
Dim localPCpath As String = "C:\..\..\Projects\test\newtest"
Dim localpath As String = Path.Combine(localPCpath, Path.GetFileName(vssItem.Name))
**vssItem.Label(msg1, msg2)**
vssItem.Checkin("Test 11 of checkin with label", localpath)
If DirectCast(vssItem.IsCheckedOut, VSSFileStatus) = VSSFileStatus.VSSFILE_NOTCHECKEDOUT Then
Console.WriteLine(vssItem.Spec + " is checked in.")
Else
Console.WriteLine(vssItem.Spec + " is checked out.")
End If
Next
报告的错误是....
System.Runtime.InteropServices.COMException未处理

我还要说，我知道这是旧软件，许多人认为MS Source Safe是垃圾邮件，但我现在仍然坚持使用它。
