while (nXpathNa.MoveToNext())
{
string cmp2 = nXpathNa.LocalName.ToString();//success is 父根节点
mXmInst.ProperEntieDetect(nXpathNa, cmp2, "Name", "Title");//验证是否存在Name， Title 属性
if (nXpathNa.MoveToFirstAttribute())
{
mXmInst.NameValueDetectB(nXpathNa.Name, nXpathNa.Value);
while (nXpathNa.MoveToNextAttribute())
{
atrName = nXpathNa.Name;
atrNameValue = nXpathNa.Value;
mXmInst.NameValueDetectB(atrName, atrNameValue);
MessageBox.Show(atrName + atrNameValue);
if (atrName.Equals("Type"))
{
bool b = System.Enum.IsDefined(typeof(Size), nXpathNa.Value);
MessageBox.Show(b + "");
}
}
}
}
[解决办法]
因为nXpathNa.MoveToNext()返回了false
[解决办法]
断点看看进不进while，如果不进就是nXpathNa.MoveToNext()为false，如果进去依次查看if、while条件是否符合
