如何以其他形式獲取richtext框值？

Question

我正在創建一個簡單的C＃windows應用程序，我想在其他from中訪問我的richtextbox值。我能夠訪問richtextbox，但是當我試圖訪問它的價值，它給了我空。

任何建議都有幫助。

Answer 1

，如果您使用的WinForms RichTextBox的，那麼你可以簡單的做了以下行動

richtextbox2.Text = richtextbox1.Text; 

如果你使用WPF的RichTextBox的看看MSDN的例子用於加載和保存自/至流TextRanges。

這裏有從MSDN

// This method accepts an input stream and a corresponding data format. The method 
// will attempt to load the input stream into a TextRange selection, apply Bold formatting 
// to the selection, save the reformatted selection to an alternat stream, and return 
// the reformatted stream. 
Stream BoldFormatStream(Stream inputStream, string dataFormat) 
{ 
    // A text container to read the stream into. 
    FlowDocument workDoc = new FlowDocument(); 
    TextRange selection = new TextRange(workDoc.ContentStart, workDoc.ContentEnd); 
    Stream outputStream = new MemoryStream(); 

    try 
    { 
     // Check for a valid data format, and then attempt to load the input stream 
     // into the current selection. Note that CanLoad ONLY checks whether dataFormat 
     // is a currently supported data format for loading a TextRange. It does not 
     // verify that the stream actually contains the specified format. An exception 
     // may be raised when there is a mismatch between the specified data format and 
     // the data in the stream. 
     if (selection.CanLoad(dataFormat)) 
      selection.Load(inputStream, dataFormat); 
    } 
    catch (Exception e) { return outputStream; /* Load failure; return a null stream. */ } 

    // Apply Bold formatting to the selection, if it is not empty. 
    if (!selection.IsEmpty) 
     selection.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold); 

    // Save the formatted selection to a stream, and return the stream. 
    if (selection.CanSave(dataFormat)) 
     selection.Save(outputStream, dataFormat); 

    return outputStream; 
}
