C#互操作-遍历行并删除
我正在使用Excel Interop处理一些Excel工作表。在工作表中,我需要遍历行,如果行中的第一个单元格为空,则需要删除整行。我尝试了以下方法-C#互操作-遍历行并删除,c#,excel,interop,excel-interop,vba,C#,Excel,Interop,Excel Interop,Vba,我正在使用Excel Interop处理一些Excel工作表。在工作表中,我需要遍历行,如果行中的第一个单元格为空,则需要删除整行。我尝试了以下方法- Excel.Range excelRange = sheet.UsedRange; foreach (Excel.Range row in excelRange.Rows) { String a = ((Excel.Range)row.Cells[Type.Missing, 1]).Value2 as String; if (a == nul
Excel.Range excelRange = sheet.UsedRange;
foreach (Excel.Range row in excelRange.Rows)
{
String a = ((Excel.Range)row.Cells[Type.Missing, 1]).Value2 as String;
if (a == null || a == "")
{
((Excel.Range)row).Delete(Type.Missing);
}
}
这根本不起作用。有什么不同的方法可以做到这一点吗
还有,有没有快速的方法来查找和删除工作表中的所有公式?假设您的Excel文件如下所示 删除行的最佳方法是使用Excel的内置功能Autofilter,该功能将过滤A列中的空白值,然后一次性删除整行 经过尝试和测试(VS 2010 Ultimate) 注意:我更改了几行,我觉得在VS 2008中可能会出错。因为我没有VS2008,所以我无法在那里测试它。如果你有任何错误,一定要让我知道,我会纠正它

第一件事第一。。。你用的是哪个VS版本?@SiddharthRout-我用的是VS2008.Ok。我有VS 2010,我将要给出的代码可能在2008年无法使用。此代码与VS 08不兼容。我们试图获取属性“End”的第11行(//~~~>Get last row in Col A)不可用。已更新帖子。现在试试看/
