方法搜索项无重载 [英] No overload for method searchitem

问题描述

我编写此代码进行搜索，但是当我从其他页面编码中调用它时，出现错误方法SearchItem的不重载为" 0"的参数".

I write this code for seaching but i got error "No overload for method SearchItem take ''0'' arguments " when i call it from other page coding.

public DataSet SearchItem(string title, string flag)
    {
        title =null;
        flag =null;
        bool @bool = false;
        StrQuery = "select * from content ";
        if (!string.IsNullOrEmpty(title))
        {
            StrQuery += " where title like ''%" + title + "%''";
            @bool = true;
        }
        if (!string.IsNullOrEmpty(flag))
        {
            StrQuery += " " + flag;
        }
        else
        {
            StrQuery += " order by contentid asc";
        }
        return objGenralMothod.ExecuteSelectQur(StrQuery);
    }

推荐答案

您的方法定义是:

Your method definition is:

public DataSet SearchItem(string title, string flag)

即它需要两个参数，两个都为字符串.
当您尝试调用它时，错误消息表示您正在使用:

I.e. it requires two parameters, both string.
When you try to call it, the error message means you are using:

DataSet ds = SearchItem();

即.您没有提供任何参数.

I.e. you have not provided either parameter.

您正在以SearchItem()的形式调用它，它应该是SearchItem("xxx"，"true")

干杯

You are invoking it as SearchItem(), it should be SearchItem("xxx", "true")

Cheers

几件事.正如格里夫(Griff)所说，这种代码对于人们攻击您的数据库而言已经成熟，真是一团糟.第二件事是，如果您不明白所收到的错误消息的含义，那么在考虑学习SQL之前，您应该专注于学习基本的C#.

A couple of things. As Griff said, this code is ripe for people to attack your database, it''s a mess. The second thing is, if you could not understand the meaning of the error message you got, you should focus on learning basic C# before you consider also learning SQL.
