asp.net 写入word （Microsoft.Office.Interop.Word）经验记录（看不明白问我）

wordApp = new Microsoft.Office.Interop.Word.ApplicationClass(); //初始化

//如果已存在，则删除
if (File.Exists((string)path))
{

}
//由于使用的是COM库，因此有许多变量需要用Missing.Value代替
Object Nothing = Missing.Value;
wordDoc = wordApp.Documents.Add(ref Nothing, ref Nothing, ref Nothing, ref Nothing);

string[] temp = strContent.Split('&');

//for (int i = 0; i < temp.Length - 1; i++)

//定义一个Word中的表格对象
