我想询问连接超时,因为我遇到了问题。 错误是
"超时已过期。从池中获取连接之前经过的超时时间。这可能已经发生,因为所有池化连接都在使用中并且达到了最大池大小。"
这样的代码会导致连接超时吗? 调用连接的最佳做法是什么?
using (var cnn = OpenExternalContractor()) //call connection string
{
var query = @"insert into interfaceRequest (requestNo,requestAssemblyName,requestApplicationName,requestFunctionName,
requestParameters,requestUserName,requestUserMail,requestDate)
values (@requestNo,@requestAssemblyName,@requestApplicationName,@requestFunctionName,
@requestParameters,@requestUserName,@requestUserMail,getDate())";
cnn.Execute(query, new
{
requestNo = requestNo,
requestAssemblyName = requestAssemblyName,
requestApplicationName = jobName.Split('-')[0],
requestFunctionName = jobName.Split('-')[1],
requestParameters = requestParameters,
requestUserName = requestUserName.Replace("\"", "\\"),
requestUserMail = userMail
});
//Call another function here that call connection string
PersonnelRepository.UpdateLastNumber(requestNamePrefix, Convert.ToInt32(lastNumber));
}
public static void UpdateLastNumber(string type, int value)
{
using (var cnn = OpenExternalContractor()) //Call connection string
{
var query = "update AutoNumber set LastNumber = " + value + " where Type = '" + type + "'";
cnn.Query<int>(query);
}
}
以下是连接字符串的代码:
protected static IDbConnection OpenExternalContractor()
{
IDbConnection dbConnection = new SqlConnection(WebConfigurationManager.ConnectionStrings["ExternalContractor"].ConnectionString);
dbConnection.Open();
return dbConnection;
}
谢谢,

使用WebConfigurationManager.ConnectionStrings["ExternalContractor"].ConnectionString
获取连接字符串时,可以通过更改此连接字符串来更改WebConfig
文件中的连接超时,例如:
Data Source=(local);
Initial Catalog=AdventureWorks;
Integrated Security=SSPI;
Connection Timeout=30
