我发现了一些关于如何创建后台工作人员来报告进度以不冻结 ui 的文章，但我没有运气。这是我正在做的事情
progressBar on Form1.cs
BackupTypes.cs - separate class
我正在使用以下内容从 BackupTypes.cs 向 progressBar 报告进度
bkup.PercentComplete += new PrecentEcompleteEventHandler(Event_PercentComplete);
这是 Event_PercentComplete
private static void Event_PercentComplete(object sender, PercentCompleteEventArgs e)
{
Form1 form = (Form1)Application.OpenForms["Form1"];
form.progressBar.Value = e.Percent;
}
如何让后台工作人员报告从 BackupTypes.cs 到 Form1.cs 的进度而不冻结 UI？
编辑后台工作者
这是我的后台工作人员，您知道现在是否在工作，也许我只需要远离它
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
Server databaseServer = new Server(dbServer);
try
{
/**
*
* Connection to the database
*
**/
databaseServer.ConnectionContext.LoginSecure = false;
databaseServer.ConnectionContext.Login = dbUser;
databaseServer.ConnectionContext.Password = dbPass;
databaseServer.ConnectionContext.Connect();
if (rbFullBackup.Checked == true)
{
dbType = "FULL";
int nDay = Convert.ToInt32(cbExperationDate.SelectedValue);
BackupTypes.FullBackup("name", "desc", databaseServer, dbDatabase, tbBackupLocation.Text, nDay, dbType);
}
if (rbDifferentialBackup.Checked == true)
{
dbType = "DIFFERENTIAL";
int nDay = Convert.ToInt32(cbExperationDate.SelectedValue);
BackupTypes.DifferentialBackup("name", "desc", databaseServer, dbDatabase, tbBackupLocation.Text, nDay, dbType);
}
if (rbLogBackup.Checked == true)
{
dbType = "LOG";
int nDay = Convert.ToInt32(cbExperationDate.SelectedValue);
BackupTypes.LogBackup("name", "desc", databaseServer, dbDatabase, tbBackupLocation.Text, nDay, dbType);
}
if (rbCompressedBackup.Checked == true)
{
dbType = "COMPRESSED";
int nDay = Convert.ToInt32(cbExperationDate.SelectedValue);
BackupTypes.LogBackup("name", "desc", databaseServer, dbDatabase, tbBackupLocation.Text, nDay, dbType);
}
if (rbMailBackup.Checked == true)
{
dbType = "MAIL";
int nDay = Convert.ToInt32(cbExperationDate.SelectedValue);
BackupTypes.MailBackup("name", "desc", databaseServer, dbMail, tbBackupLocation.Text, nDay, dbType);
}
}
catch (SqlServerManagementException ex)
{
/**
*
* Write errors to log file
*
**/
if (LogStatus == true)
{
Output(ex.Message);
if (DebugStatus == true)
{
Output(ex.ToString());
}
Output(" ");
}
}
finally
{
if (databaseServer.ConnectionContext.IsOpen)
{
/**
*
* Close the connection to the database
*
**/
databaseServer.ConnectionContext.Disconnect();
}
}
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
progressBar.Value = e.ProgressPercentage;
}
然后从我的 BackupTypes.cs 报告更改
form.backgroundWorker1.ReportProgress(e.Percent);
