我需要知道文本框中的总数 [英] I need to know the total count in the textbox

问题描述

有人可以告诉我如何获取文本框中列表框的项总数.请使用编码简要说明一下.\

can someone pls tell me how can i get the total count of items of listbox in the textbox. pls explian me briefly with coding.\

推荐答案

大多数项目集合都具有count属性.
从该属性中获取计数，然后将其显示在文本框中.

t.Text = collections.Count

Most item collections have a count property.
Pick up the count from this property and then display it in your text box.

t.Text = collections.Count

向您的查询添加输出参数以获取从数据库检索到的行数.然后使用该输出参数.

Add an output parameter to your query to get the number of rows retrieved from database. Then use that output parameter.

@Count int OUTPUT

SELECT * FROM list

SET @Count = @@RowCount
