我正在将 excel 工作表转换为 xml 格式。我面临的问题是我有很多没有任何数据的字段。对于那些，我得到一个像这样的空白标签：
<event-name />
我想要的是这个标签应该是这种格式：
<event-name></event-name>
string Title = dsPushTable.Rows[i]["title"].ToString();
string Shortdescription = dsPushTable.Rows[i]["short-description"].ToString();
string sampleimageshref1 = dsPushTable.Rows[i]["sampleimageshref"].ToString();
string sampleimageshref2 = dsPushTable.Rows[i]["sampleimageshref1"].ToString();
string variantshref1 = dsPushTable.Rows[i]["variantshref1"].ToString();
string variantshref2 = dsPushTable.Rows[i]["variantshref2"].ToString();
string start = dsPushTable.Rows[i]["life-cyclestart"].ToString();
string end = dsPushTable.Rows[i]["life-cycleend"].ToString();
string contentcpid = dsPushTable.Rows[i]["content-cp-id"].ToString();
string Keyw = dsPushTable.Rows[i]["keywords"].ToString();
string categoriesref1 = dsPushTable.Rows[i]["categoriesref1"].ToString();
string categoriesref2 = dsPushTable.Rows[i]["categoriesref2"].ToString();
string Moviename = dsPushTable.Rows[i]["movie-name"].ToString();
string actorname = dsPushTable.Rows[i]["actor-name"].ToString();
string lyricist = dsPushTable.Rows[i]["lyricist"].ToString();
string singername = dsPushTable.Rows[i]["singer-name"].ToString();
string Label = dsPushTable.Rows[i]["label"].ToString();
