看一下代码 为什么就是释放不了。。。。。。。。。
Excel.Application XApp = new Excel.ApplicationClass();
//XApp.Visible = true;

for (int i = 1; i < oRange.Cells.Rows.Count; i++)
{
for (int j = 1; j < oRange.Cells.Columns.Count; j++)
{
Excel.Range range = (Excel.Range)oRange[i, j];
if (range.Value2 != null)

}
else
{
Console.WriteLine("字段不存在:{0}",str);
}
}
}
// Console.WriteLine(range.Value2.ToString());
}
}
