{C}但它的NT正常工作......在ComboBox不填写具有独特的数据
mkcm2011

codepreSqlCommandmycommand=newSqlCommand(spanclass="code-string""/spanspanclass="code-string"selectid,namefromtablename"/span,myCon);SqlDataReaderdr=mycommand.ExecuteReader();spanclass="code-keyword"while/span(dr.spanclass="code-keyword"Read/span()){id_cmb.Items.spanclass="code-keyword"Add/span(dr.GetValue(spanclass="code-digit"0/span));name_cmb.Items.spanclass="code-keyword"Add/span(dr.GetValue(spanclass="code-digit"1/span));}/pre/code的你上面的SQL查询不能满足您的条件，不管你想要......如果你想在ComboBox中显示不同的值，那么你将无法找到该记录的唯一ID（如果有不同的ID相同的名称）.........因此，无论是具有独特的名称更改数据库表ID或不选择的ID{体C3}
