问题描述

如何在wpf中从数据库加载数据时显示加载图像？

解决方案

您是否考虑过BackgroundWorker类，

 BackgroundWorker bg =  new  BackgroundWorker（）; 
 bg.DoWork + = bg_DoWork; 
 bg.RunWorkerCompleted + = bg_RunWorkerCompleted; 

然后在方法中你可以这样做

< pre lang =c＃> void bg_RunWorkerCompleted（ object sender，RunWorkerCompletedEventArgs e）
{
// 隐藏图片显示数据
}

void bg_DoWork（ object sender，DoWorkEventArgs e）
{
// 显示图片加载数据
}

解决方案

Have you thought about BackgroundWorker Class,

BackgroundWorker bg = new BackgroundWorker();
bg.DoWork += bg_DoWork;
bg.RunWorkerCompleted += bg_RunWorkerCompleted;

Then In methods you can do like

void bg_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
           //hide image show data
}

void bg_DoWork(object sender, DoWorkEventArgs e)
{
            //show image load data
}
