函数不返回sqlconnection [英] Function not returning sqlconnection

问题描述

我创建了一个函数来获取动态的sql连接字符串，

但是当我调用这个函数时它没有返回值



< b>我尝试了什么：



功能衰减

I made a function to get dynamic sql connection string,
but its not returning value when I am calling this function

What I have tried:

Function Decleration

public string GetConnectionString()
   {
       //return "Data Source=DELL\\HRMS; " +
       //    " Integrated Security=true;" +
       //    "Initial Catalog=CL1COM0032;";

       Common cmn = new Common();
       SqlConnection connn = new SqlConnection();
       connn = cmn.getConnectionForCompany(uInfo.prDBName);
       connn.Open();
       return connn.ToString();
   }

函数调用

Function Calling

string connectionString = GetConnectionString();

推荐答案

ToString方法不返回连接字符串;你正在寻找 ConnectionString [ ^ ]属性：

The ToString method doesn't return the connection string; you're looking for the ConnectionString[^] property:

public string GetConnectionString()
{
    return cmn.getConnectionForCompany(uInfo.prDBName).ConnectionString;
}
