ASP.NET - 服务器连接重置

Question

我有一个网站，不时需要我对Access数据库进行批量更新，为了方便起见，我创建了一个包含大文本框的运行一次和删除页面，一个验证码和一个硬编码的强密码。当我对数据库的本地副本运行时，我没有任何问题，但是当我在服务器上运行它时，点击提交后大约3秒钟就会收到“与服务器重置的连接”。不幸的是，主机环境超出了我的范围，所以当发生这种情况时，我无法查看任何服务器端日志。我不知道这可能是什么原因造成的，所以我希望你们可以看看。

这段代码有点难看，因为我真的不在乎花很多时间在上面（有些是由另一个开发者编写的）。无论如何，我没有看到任何明显的功能问题。

protected void btnRunBatch_Click(object sender, EventArgs e) 
{ 
    if (Page.IsValid) 
    { 
     ArrayList queries = GetSqlStatementArray(); 
     string results = string.Empty; 

     try 
     { 
      BatchSQLInsert(Application["DBPath"].ToString(), queries); 

      if (queries.Count > 0) 
      { 
       results = "<b>Batch Operation Completed Successfully.</b><br /><br />"; 
       results += "The following queries were executed:"; 
       results += "<ul>"; 
       foreach (string query in queries) 
       { 
        results += "<li>" + query + "</li>"; 
       } 
       results += "</ul>"; 

       this.tbxBatchStatement.Text = string.Empty; 
      } 
      else 
      { 
       results = "<b>No queries to execute.</b>"; 
      } 
     } 
     catch (Exception ex) 
     { 
      results = "<b>Execution Errors Encountered:</b><br />"; 
      results += "<ul><li>" + ex.Message + "</li></ul>"; 
     } 

     this.phResults.Controls.Add(new LiteralControl(results)); 
    } 
} 

private ArrayList GetSqlStatementArray() 
{ 
    ArrayList queries = new ArrayList(); 
    string[] lines = this.tbxBatchStatement.Text.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); 
    string lineBuffer = string.Empty; 

    foreach (string line in lines) 
    { 
     if (lineBuffer == string.Empty) 
     { 
      if ((line.ToUpper().StartsWith("SELECT") || line.ToUpper().StartsWith("INSERT") || line.ToUpper().StartsWith("UPDATE") || line.ToUpper().StartsWith("DELETE"))) 
      { 
       if (line.EndsWith(";")) 
        queries.Add(line); 
       else 
        lineBuffer = line; 
      } 
     } 
     else 
     { 
      lineBuffer += " " + line; 
      if (line.EndsWith(";")) 
      { 
       queries.Add(lineBuffer); 
       lineBuffer = string.Empty; 
      } 
     } 
    } 
    return queries; 
} 

public static void BatchSQLInsert(string DBPath, System.Collections.ArrayList sqlArray) 
{ 
    System.Data.OleDb.OleDbCommand cmd = null; 
    System.Data.OleDb.OleDbConnection conn = null; 
    System.Data.OleDb.OleDbTransaction myTrans = null; 
    int intRecsReturned = 0; 
    int i = 0; 

    if (sqlArray.Count > 0) 
    { 
     cmd = new System.Data.OleDb.OleDbCommand(); 
     conn = GetConnection(DBPath); 
     myTrans = conn.BeginTransaction(); 

     try 
     { 
      cmd.CommandType = System.Data.CommandType.Text; 
      cmd.Connection = conn; 
      cmd.Transaction = myTrans; 
      while (i < sqlArray.Count) 
      { 
       cmd.CommandText = (string)(sqlArray[i]); 
       intRecsReturned = cmd.ExecuteNonQuery(); 
       i++; 
      } 
      myTrans.Commit(); 
      conn.Close(); 
     } 
     catch (Exception eee) 
     { 
      myTrans.Rollback(); 

      throw new Exception("BatchSQLInsert() failed-" + eee.Message + "\r\nArray-" + sqlArray.ToString()); 
     } 
     finally 
     { 
      if (conn != null) 
       conn.Dispose(); 
      if (cmd != null) 
       cmd.Dispose(); 
     } 
    } 
}

听起来过程太长时间运行，则可能需要在IIS中进行调整超时设置... :(

，我知道你不能，对不起，不是真的helpful-
