问题描述
我想用C#来运行查询,我得到以下问题
i trying to run query using C#, i am getting the following problem
在ConnectionString中未指定OLE DB提供程序。一个例子是,供应商= SQLOLEDB;
我的code
string strConString = System.Configuration.ConfigurationManager.ConnectionStrings["WorkflowConnStr"].ConnectionString.ToString();
string sqlstr = "select * from table"
OleDbConnection myConnection = new OleDbConnection(strConString);
try
{myConnection.Open();}
catch (Exception err)
{ System.Diagnostics.Debug.WriteLine(err.Message); }
OleDbCommand myCommand = new OleDbCommand(sqlstr, myConnection);
OleDbDataReader reader = myCommand.ExecuteReader();
的web.config
web.config
<add name="WorkflowConnStr" connectionString="Data Source=Server;Initial Catalog=DBName;user id=usr;password=password" providerName="System.Data.OleDb.OleDbConnection"/>
什么建议吗?
推荐答案
尝试添加这对您的连接字符串,
Try adding this to your connection string,
Provider=SQLNCLI10.1
因此,这将是;
So it would be;
<add name="WorkflowConnStr" connectionString="Data Source=Server;Initial Catalog=DBName;user id=usr;password=password;Provider=SQLNCLI10.1" providerName="System.Data.OleDb.OleDbConnection"/>
