C# 将字符串发送到另一页

您好，在我的母版页上，我有一个搜索区域，但我的搜索代码位于另一个名为search.aspx的页面（内容页）

protected void Page_Load(object sender, EventArgs e)
{
    string search = Request.QueryString["search"];
    if (!string.IsNullOrEmpty(search))
    {
       PopulateWallPosts(search);
    }
}

private void PopulateWallPosts(string search)
{
   //my search query code
}

当我单击按钮对数据库进行搜索查询时，我需要将字符串从母版页发送到搜索页并重定向

Search.aspx代码：

protected void Page_Load(object sender, EventArgs e)
    {

    }
    private void PopulateWallPosts(string search)
    {
       //my search query code
    }

protected void Button2_Click(object sender, EventArgs e)
{


    string search = TextBox2.Text;

    PopulateWallPosts(search);
    // this method works fine on local page
    // how do I send this to Search.aspx so when button is clicked im redirected to search.aspx and the content of search populates my wallposts?

    }
}

母版页：

protected void Page_Load(object sender, EventArgs e)
    {

    }
    private void PopulateWallPosts(string search)
    {
       //my search query code
    }

protected void Button2_Click(object sender, EventArgs e)
{


    string search = TextBox2.Text;

    PopulateWallPosts(search);
    // this method works fine on local page
    // how do I send this to Search.aspx so when button is clicked im redirected to search.aspx and the content of search populates my wallposts?

    }
}

您可以设置按钮/链接的属性：

<asp:Button PostBackUrl="Search.aspx" ID="search" runat="server" Text="Search" />

只需将搜索框重定向到搜索页面，在查询字符串上传递参数即可

Search.aspx

protected void Page_Load(object sender, EventArgs e)
{
    string search = Request.QueryString["search"];
    if (!string.IsNullOrEmpty(search))
    {
       PopulateWallPosts(search);
    }
}

private void PopulateWallPosts(string search)
{
   //my search query code
}

母版页：

protected void Button2_Click(object sender, EventArgs e)
{
    string search = TextBox2.Text;

    Response.Redirect("Search.aspx?search=" + Server.UrlEncode(search));
}

@Garrith Graham，文本框在哪里？在母版页中？如果Search.aspx是否来自同一个master？@Garrith Graham，那么您应该能够

var txtSearch=（TextBox）PreviousPage.master.FindControl（“TextBox1”）

获取

Search.aspx

中相应的文本框，并使用

.Text

属性获取文本。
