asp.net - Excel 到 SQL Server 数据导入错误：没有为一个或多个必需参数提供值

Question

我正在尝试将数据从 Excel 导入 SQL Server 数据库。但是当我运行它时，一切都没有上传，我运行它时出现了这个错误：

没有为一个或多个必需参数指定值。

任何人都可以帮忙吗？这是我的代码：

protected void Button1_Click1(object sender, EventArgs e)
{
    String strConnection = "Data Source="";Initial Catalog="";Integrated Security=True";
    //file upload path
    string path = FileUpload1.PostedFile.FileName;
    //Create connection string to Excel work book
    string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;Persist Security Info=False";
    //Create Connection to Excel work book
    OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);
    //Create OleDbCommand to fetch data from Excel
    OleDbCommand cmd = new OleDbCommand("Select [ID],[StudentName],[CLass],[NRIC],[FixedAmount] from [Sheet1$]", excelConnection);
    excelConnection.Open();
    OleDbDataReader dReader;
    dReader = cmd.ExecuteReader();
    SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);
    //Give your Destination table name
    sqlBulk.DestinationTableName = "StudentParticulars";
    sqlBulk.WriteToServer(dReader);
    excelConnection.Close();
}
