Question

我正在使用C＃环境，我有以下代码，我测试过它在Visual Basic .Net下工作：

Private Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound  
    if e.Row.RowType = DataControlRowType.DataRow then

        Dim RowNum as Integer
        RowNum = e.Row.RowIndex

        if RowNum mod 2 = 1 then
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#DDDDDD'")
        else
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'")
        end if

        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='DeepSkyBlue'")
        e.Row.Attributes("onclick") = Me.Page.ClientScript.GetPostBackClientHyperlink(Me.GridView1, "Select$" & e.Row.RowIndex) 
    End If
End Sub

因此，我尝试将其转换为C＃语言，但无法使其正常工作。

C＃

不知何故，“e.Row.Attributes("onclick")”适用于VB，但不适用于C＃

private void GridView1_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int RowNum = e.Row.RowIndex;
        if (RowNum % 2 == 1)
        {
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#DDDDDD'");
        }
        else
        {
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
        }

        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='DeepSkyBlue'");
        e.Row.Attributes("onclick") = this.Page.ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" & e.Row.RowIndex);
    }
}

将其更改为：

e.Row.Attributes["onclick"] = this.Page.ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + e.Row.RowIndex);

C＃数组中的

是用括号而不是parantheses调用的。另外，我们使用加号而不是＆符号来连接字符串。

您也可以这样做（以匹配其正上方的代码）：

e.Row.Attributes.add("onclick", this.Page.ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + e.Row.RowIndex));

gridview中备用行的颜色
