打开与OLEDB的连接终止代码

Question

我正在尝试在C＃中创建一个DBF文件。不知何故，当我试图打开与OLEDB的连接时，该程序将终止而不会引发例外。以下是代码：

private void CreateDBFFile()
    {
        try
        {
            using (var dBaseConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; " + @" Data Source=k:Temp; " + @"Extended Properties=dBase IV"))
            {
                dBaseConnection.Open();
                string createTableSyntax =
                    "Create Table Person " +
                    "(Name char(50), City char(50), Phone char(20), Zip decimal(5))";
                var cmd = new OleDbCommand(createTableSyntax, dBaseConnection);
                cmd.ExecuteNonQuery();
            }
        }
        catch (Exception ex)
        {
            string x = ex.Message;
        }
    }

错误在此处丢弃：

dBaseConnection.Open();

我检查了事件日志，这也无济于事。以下是事件日志中的错误日志：'

任何帮助将不胜感激。

Answer 1

您的连接方式不是理想的。

做这件事，然后逐步浏览代码，您应该能够得到异常或可以工作：将您的连接字符串放入Web.config。

  <connectionStrings>
    <add name="Connection" connectionString="Data Source=k:Temp; xtended Properties=dBase IV Provider=Microsoft.Jet.OLEDB.4.0" />    
  </connectionStrings>

string connection = ConfigurationManager.ConnectionStrings["Connection"].ConnectionString;
           using (OleDbConnection dBaseConnection = new OleDbConnection(connection))
           {
               if (dBaseConnection.State == ConnectionState.Closed)
               {
                   dBaseConnection.Open();
               }
           }

Answer 2

一旦我从连接字符串删除此行

     "Extended Properties=dBase IV ". 

代码开始工作。
