BackgroundWorker的在C＃ [英] Backgroundworker in C#

问题描述

其实，我需要提示加载图像throwugh backgrounderworker，每当一个特定的功能在这里被调用
是我的代码：

Actually, i need to prompt a loading image throwugh backgrounderworker, whenever a particular function is been invoked here is my code :

 private void bgwFile_DoWork(object sender, DoWorkEventArgs e)
 {
        FormFieldsLoad();      
 }

private void bgwFile_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    if (e.Cancelled == true)
    {
        Status.Text = "cancelled";
    }
    else if (e.Error != null)
    {
    }

    picprocess.SendToBack(); 
    Status.Text = "Completed";         
}

 //Below Method where i have called RunWorkerAsync()
private void buttonUpload_Click(object sender, EventArgs e)
{
    LoadFile(pdfFullPath, txtPassword.Text);
    form = document.getDocumentCatalog().getAcroForm();
    java.util.List FieldTypes = form.getFields();
    availableFieldsTable.Clear();
    btnLoad.Enabled = false;     
    Status.Text = "Document loaded successfully!!!";

    picprocess.BringToFront();  
    bgwFile.RunWorkerAsync();
}

在运行上面的代码，它调用加载图片，但没有输出被显示它不断显示加载图片..它不叫了 RunWorkerCompleted

任何一个可以帮助我出PLS

Can any one help me out pls

感谢

推荐答案

你分配事件处理程序？

Did you assign the event handlers?

bwgFile.DoWork += bgwFile_DoWork;
bwgFile.RunWorkerCompleted += bgwFile_RunWorkerCompleted;

您确定 FormFieldsLoad 终止？
