Question

我想将图像添加到我的aspx类中的表中的特定单元格。现在我有一个if语句改变了单元格的颜色，我想要另一个if语句，它将图像添加到同一个单元格。任何想法如何做到这一点？

public partial class FutureDelivery : System.Web.Mvc.ViewPage
{

    protected void Page_Load(object sender, EventArgs e)
    {
        // Response.Cache.SetCacheability(HttpCacheability.NoCache);
        errormsg.Text = "";
        FutureDeliveryModel theModel = (FutureDeliveryModel)ViewData["FutureDelivery"];
      // litSite.Text = Site.getSite();
        //DataTable StockTable = (DataTable)ViewData["Future"];
        DataTable StockTable =  theModel.GetFuture();
        DataView StockView = StockTable.DefaultView;
        StringBuilder SB = new StringBuilder();
        SB.Append("<table class=\"display\" id=\"dt\" style=\"align: left; width: 99%;\" ");
        SB.Append("rules=\"all\" border=\"1px\" ");
        SB.Append("cellspacing=\"0px\" cellpadding=\"4px\">");

        SB.Append("<thead>");
        SB.Append("<tr></tr>");
        SB.Append("<tr style=\"background-color: Silver; color: #212121; ");
        SB.Append("font-weight: bold\">");
        // Header 
        foreach (DataColumn aColumn in StockTable.Columns)
        {

                    }

                    SB.Append(">");


                    if (aColumn.ColumnName.ToString().Equals("Export Quantity"))
                    {
                        if (export == 0)
                        {
                            SB.Append(" ");

可能你只需要一个字符串追加，如下，

if(condition){
    sb.Append("<img src=\"images/pic.jpg\" alt=\"Sample Photo\" />");
}

images/pic.jpg是图像的路径。

我想在我的aspx类中添加一个图像到我表中的特定单元格
