如何将变量传递给另一个命名空间？ [英] How to pass a variable to another namespace?

问题描述

我必须在此处将计数值传递给另一个命名空间。我有2个类Select.cs和Value.cs。 Select.cs具有以下代码：

  public   bool 登录（字符串用户名，字符串密码）
 {
 < span class =code-keyword> string  strinvselect =  string  .Format（ < span class =code-string> select * from newlog where 
 pass ='{0}'，Password）; 
 
 DataTable dtlog = ExecuteStatement（strinvselect）; 
 
  if （dtlog.Rows.Count ==  1 ）
 {
  string  strvalue =  string  .Format（ 选择* FROM login WHERE uid = 
'{0}'，UserName）; 
 
 DataTable newlogin = ExecuteStatement（strvalue）; 
 
 尝试 
 {
 如果（newlogin。 Rows.Count ==  1 ）
 {
 loginStatus =  true ; 
} 
} 
  catch （例外情况）
 {
 loginStatus = 假; 
} 
 
  return  loginStatus; 
} 
} 

我必须创建一个计数值if（newlogin.Rows.Count == 1 ），count = 1并且Value.cs中应该可以使用此值来检查功能。在Value.cs中，调用函数getdetails（）。在这里我需要检查

  if （count ==  1 ）
 {
 getdetails（）; 
} 
 其他 
 {
  //  < span class =code-comment>调用另一个函数 
} 

解决方案

命名空间并不真正相关在这里，问题是您需要从不同的类访问变量。您拥有特定于用户的全局变量的方式是Session，因此将值存储在Session变量中，让其他类访问Session变量。



您的登录功能

会话[  myData ] = someIntValue; 

您的超值功能

  int  x; 
 
  if （会话[  myData] ==  null ）
 {
  //  处理未设置的数据 
} 
  else  
 { 
x =（ int ）会话[  myData ]; 
}

I have to pass a count value to another namespace here. I have 2 classes Select.cs and Value.cs. Select.cs has the following code:

public bool Login(string UserName, string Password)
    {
        string strinvselect = string.Format("select * from newlog where
                              pass='{0}'", Password);

        DataTable dtlog = ExecuteStatement(strinvselect);

        if (dtlog.Rows.Count == 1)
        {
            string strvalue = string.Format("Select * FROM login WHERE uid= 
                                           '{0}'", UserName);

            DataTable newlogin = ExecuteStatement(strvalue);

            try
            {
                if (newlogin.Rows.Count == 1)
                {
                    loginStatus = true;
                }
            }
            catch (Exception ex)
            {
                loginStatus = false;
            }

            return loginStatus;
        }
    }

I have to create a count value if(newlogin.Rows.Count == 1), count=1 and this value should be available in Value.cs to check a functionality. In Value.cs a function getdetails() is called. Here I need to check

if (count == 1)
        {
            getdetails();
        }
        else
        {
            // call another function
        }

解决方案

Namespaces are not really relevant here, the issue is that you need to access the variable from a different class. The way you have "global" variables that are specific to the user is the Session, so store the value in a Session variable and have your other class access the Session variable.

Your login function

Session["myData"] = someIntValue;

Your Value function

int x;

if (Session["myData"] == null)
{
   // handle the data not being set
}
else
{
   x = (int)Session["myData"];
}
