c#dataread 读取数据库decimal类型的字段值

Posted 2023-03-26

if (sqlread.Read()) labKH.Text = sqlread["KH"].ToString(); labXM.Text = sqlread["XM"].ToString(); labLX.Text = sqlread["LX"].ToString(); labJB.Text = sqlread["JB"].ToString(); labJF.Text = sqlread["JF"].ToString(); labXFJE.Text = sqlread["XFJE"].ToString(); labXFCS.Text = sqlread["XFCS"].ToString(); labZT.Text = sqlread["ZT"].ToString(); labXFJE.Text = sqlread["XFJE"].ToString();这句是错误的XFJE在数据库中的类型是decimallabXFCS.Text = sqlread["XFCS"].ToString();这句也是错误的XFCS在数据库中的类型是float请问那两句要怎么改过来了

参考技术A labXFJE.Text
=
sqlread["XFJE"].ToString();labXFCS.Text
=
sqlread["XFCS"].ToString(); 这2句不该报错，如果报错应该是数据库中字段为空，发生了空引用错误。改为如下即可：labXFJE.Text
=
sqlread["XFJE"]??sqlread["XFJE"].ToString();labXFCS.Text
=
sqlread["XFCS"]??sqlread["XFCS"].ToString();？
