public void CreateFileOutput(object parameter)
{
    TransactFileCreation();

    WPFMessageBox.Show("test", "Process completed successfully.");
}

public void TransactFileCreation()
{
    if (BatchFolderPath == null)
    {
         WPFMessageBox.Show("test", "Select a Batch folder");
         return;
    }

But in my case, it again go to the main function and displaying msg box present in that. How to stop execution after once message box is displayed. Provide me a solution. Thanks.

推荐答案

您可以返回布尔值:

public bool TransactFileCreation()
{
    if (BatchFolderPath == null)
    {
         WPFMessageBox.Show("test", "Select a Batch folder");
         return false;
    }
    // code..
    return true;
}

然后您这样调用:

public void CreateFileOutput(object parameter)
{
    if (!TransactFileCreation())
        return;

    WPFMessageBox.Show("test", "Process completed successfully.");
}
