Question

有一行＆＃34;正确＆＃34;我的数据库中的文字。但是if条件永远不会成立。

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            Label lblremark = (Label)e.Row.FindControl("lblremark");
            if (lblremark.Text == "Correct")
            {
                e.Row.ForeColor = System.Drawing.Color.Black;
                e.Row.BackColor = System.Drawing.Color.Cyan;
            }
            else
            {
                e.Row.ForeColor = System.Drawing.Color.Black;
                e.Row.BackColor = System.Drawing.Color.Orange;
            }
        }   
    }

Answer 1

如果您正确找到标签，请尝试此操作

if (lblremark.Text.Trim().ToLower().Equals("correct"))
