我想在asp.net中創建Excel工作表。我已經完成了代碼，它在本地系統中工作正常，但是當我在服務器上測試它時，它會出現以下錯誤。如何在asp.net中創建Excel文件
檢索COM類工廠CLSID {00024500-0000-0000-C000-000000000046}組件失敗，原因是以下錯誤：80070005。
我的代碼。
private static System.Data.DataTable GetDataSet()
{
System.Data.DataTable dt = new System.Data.DataTable("Table");
dt.Columns.Add("Name", Type.GetType("System.String"));
dt.Columns.Add("Address", Type.GetType("System.String"));
dt.Columns.Add("Phone", Type.GetType("System.String"));
DataRow dr = dt.NewRow();
dr["Name"] = "Balaji Selvarajan";
dr["Address"] = "Reddiyur";
dr["Phone"] = "000-000-0000";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["Name"] = "Balaji S";
dr["Address"] = "Kattumannar Koil";
dr["Phone"] = "000-000-0000";
dt.Rows.Add(dr);
return dt;
}
private static void DataSetToExcel(System.Data.DataTable dt, Boolean generateIdentity)
{

我無法解決這個問題，請幫助我。請儘快給我解決方案。
我正在使用Asp.net C＃。

上使用Office服務器（如從asp.net）是[不支持]（http://support.microsoft.com/kb/257757）。有幾個組件（也是免費的），可以讓你從asp.net生成Excel文件。 – 2015-02-10 10:38:22
你可以給我這些免費軟件組件的URL用於生成Excel文件 – 2015-02-10 11:06:32
