在c#中可以操作office的excel，这个是比较简单，直接引入类库操作。操作wps中的excel比其比较麻烦。
第一步：首先将wps的相关COM组件添加至引用. 工程->添加引用->COM->Kingsoft ET 2.0 Object Library / Upgrade Kinsoft ET 3.0 Object Library
第二步：Using KSO;Using ET;(导入Kingsoft ET 2.0 Object Library时引用)
Using EXCEL;(导入Upgrade Kinsoft ET 3.0 Object Library时引用)
第三步：将数据存储在c#内存中定义的数据表中。
static void Dataprocessing(String tagid,String actionid)
{
System.Data.DataTable dt = new System.Data.DataTable(); //定义数据表变量
//数据库中执行查询的SQL语句
string sql = string.Format("SELECT * from RSSIData where ActionId='"+actionid+"'");
if (connection.State == ConnectionState.Closed)
{
connection.Open();
}
SqlCommand cmd = new SqlCommand(sql, connection);
SqlDataReader reader = cmd.ExecuteReader();
//生成表格的每列的标题（以我的程序为例）
for (int i = 0; i < 7; i++)
{
if (i == 0){dt.Columns.Add("读写器ID", typeof(string)); }
else if(i==1) { dt.Columns.Add("标签ID", typeof(string)); }
else if (i == 2) { dt.Columns.Add("标签负载", typeof(string)); }
else if (i == 3) { dt.Columns.Add("A通道RSSI值", typeof(string)); }
else if (i == 4) { dt.Columns.Add("B通道RSSI值", typeof(string)); }
else if (i == 5) { dt.Columns.Add("测试时间", typeof(string)); }
else if (i == 6) { dt.Columns.Add("数据标识ID", typeof(string)); }
}
//根据数据库查询的结果，一一将数据填写在对应的dt行中
while(reader.Read())
{
DataRow dr = dt.NewRow();
for (int j = 0; j <7; j++)//for循环一次，生成一行数据
{
if (j == 0){ dr[j] = reader["ReaderId"]; }
else if(j==1){ dr[j] = reader["TagId"];}
else if (j == 2) { dr[j] = reader["Payload"]; }
else if (j == 3) { dr[j] = reader["RSSI"]; }
else if (j == 4) { dr[j] = reader["RSSIB"]; }
else if (j == 5) { dr[j] = reader["CollectTime"]; }
else if (j == 6) { dr[j] = reader["ActionId"]; }
}
dt.Rows.Add(dr);
}
string s = OutputWPSExcel(dt, "第二组小方格测试的四个标签数据报表", "C:\\users\\acer\\Desktop\\导师的\\定位数据统计\\");
Console.Write(s);
}
第四步：将dt中的数据存储在wps的excel中
///
/// 将DataTable的数据导出显示为报表(使用WPS)
///
/// 要导出的数据
/// 导出报表的标题
/// 保存文件的路径
///
static string OutputWPSExcel(System.Data.DataTable dt, string strTitle, string FilePath)

DateTime afterTime = DateTime.Now;
filename =FilePath+ strTitle + "_" + DateTime.Now.ToString("yyyyMMddHHmmssff") + ".xls";
//保存文件
objWorkBook.SaveAs(filename, missing, missing, missing, missing, missing, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing, missing);
