Question

我使用c＃创建了Web应用程序，将excel文件导入Microsoft Dynamics CRM。我使用Fileupload导入excel文件。

以下是代码段：

导入按钮：

if (FileUpload1.PostedFile != null)
    {
        string FilePath = Path.GetFileName(this.FileUpload1.FileName);
        string FileName = Server.MapPath(Path.GetFileName(FilePath));
        string Extension = Path.GetExtension(this.FileUpload1.FileName);
        DataTable dt = ImportData(FileName, Extension);

这是ImportData代码：

private DataTable ImportData(string Filepath, string Extension)
{
    string connString = "";
    DataTable dt = new DataTable();

    switch (Extension)
    {
        case ".xls":
            connString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString;
            break;
        case ".xlsx":
            connString = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString;
            break;
    }

    connString = string.Format(connString, Filepath, 1);

    try
    {
        OleDbConnection excelConn = new OleDbConnection(connString);
        OleDbCommand excelCmd = new OleDbCommand();
        OleDbDataAdapter oda = new OleDbDataAdapter();
        excelCmd.Connection = excelConn;

        excelConn.Open();
        DataTable dtexcelschema;
        dtexcelschema = excelConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
        string SheetName = dtexcelschema.Rows[0]["TABLE_NAME"].ToString(); **The Error Come from this line**
        excelConn.Close();

        excelConn.Open();
        excelCmd.CommandText = "Select * from [" + SheetName + "]";
        oda.SelectCommand = excelCmd;
        oda.Fill(dt);
        excelConn.Close();
    }
    catch (Exception ex)
    {
       Label1.Text = ex.Message;
    }
    return dt;
}

当我尝试将excel导入CRM时。我得到了这样的信息：＆＃34; 0号位没有排。＆＃34;

我不知道这里发生了什么。实际上在我创建Web应用程序之前，我使用此代码创建了Windows应用程序，并成功导入数据。但是，当我将此代码复制到Web应用程序中时，我收到了该消息。

这是web config中的连接字符串：

<add name ="Excel03ConString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'"/>
<add name ="Excel07ConString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 12.0;HDR={1}'"/>

使用此：

string Filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
        string Extension = Path.GetExtension(FileUpload1.PostedFile.FileName);
        string Folderpath = ConfigurationManager.AppSettings["FolderPath"];

        string Filepath = Server.MapPath(Folderpath + Filename);
        FileUpload1.SaveAs(Filepath);

        DataTable dt = ImportData(Filepath, Extension);

从excel导入数据时出现ASP.NETC＃错误
