我的c#应用程序以下列方式将数据导出到xls文件(下面提供了代码,简化了一点,因为原始代码相当大):
使用Excel 2007,一切正常。使用Excel 2010时,它有时会挂起工作簿Save()方法。没有错误,只是挂起(因为它正在等待对话之类的东西)。
我找不到任何模式:50个电话中有近1个挂起;重复的同一个电话可以挂起或不挂起。
有什么想法会发生这种情况吗?

// Perform actions to save data into worksheet

finally

}
ComObject.Release(workbooks);
app.Quit();
ComObject.Release(app);
app = null;
答案 0 :(得分:0)
不确定为什么会出现这种情况,但如何尝试逐页保存。
它不必一次保存很多张?
