Question

我已经获得了一个相当大的excel文件，每行包含一个来自我们的oracle数据库的clob转储，其中一个可能如下所示：

{\rtf1\ansi\deff0\deftab708{\fonttbl{\f0\fnil\fcharset0 Courier New;}{\f1\fnil\fcharset0 Arial;}{\f2\fnil\fcharset0 MS Sans Serif;}{\f3\fnil\fcharset0 Times New Roman;}{\f4\fnil\fcharset238 Times New Roman CE;}{\f5\fnil\fcharset204 Times New Roman Cyr;}{\f6\fnil\fcharset161 Times New Roman Greek;}{\f7\fnil\fcharset162 Times New Roman Tur;}{\f8\fnil\fcharset186 Times New Roman Baltic;}}{\colortbl\red0\green0\blue0;\red255\green0\blue0;\red0\green0\blue255;\red0\green255\blue255;\red0\green255\blue0;\red255\green0\blue255;\red128\green0\blue128;\red255\green255\blue0;\red255\green255\blue255;\red0\green0\blue128;\red0\green128\blue128;\red0\green128\blue0;\red128\green128\blue0;\red128\green0\blue0;\red128\green128\blue128;\red255\green255\blue255;}\paperw11906\paperh16838\margl1417\margr1417\margt1417\margb1417{\*\pnseclvl1\pnucrm\pnstart1\pnhang\pnindent720{\pntxtb}{\pntxta{.}}}{\*\pnseclvl2\pnucltr\pnstart1\pnhang\pnindent720{\pntxtb}{\pntxta{.}}}{\*\pnseclvl3\pndec\pnstart1\pnhang\pnindent720{\pntxtb}{\pntxta{.}}}{\*\pnseclvl4\pnlcltr\pnstart1\pnhang\pnindent720{\pntxtb}{\pntxta{)}}}{\*\pnseclvl5\pndec\pnstart1\pnhang\pnindent720{\pntxtb{(}}{\pntxta{)}}}{\*\pnseclvl6\pnlcltr\pnstart1\pnhang\pnindent720{\pntxtb{(}}{\pntxta{)}}}{\*\pnseclvl7\pnlcrm\pnstart1\pnhang\pnindent720{\pntxtb{(}}{\pntxta{)}}}{\*\pnseclvl8\pnlcltr\pnstart1\pnhang\pnindent720{\pntxtb{(}}{\pntxta{)}}}{\*\pnseclvl9\pnlcrm\pnstart1\pnhang\pnindent720{\pntxtb{(}}{\pntxta{)}}}{\pard\ql\li0\fi0\ri0\sb0\sl\sa0 \plain\f3\fs24\cf0 FOO FOO FOO \'85\'85. \'85\'85..}}

现在，通过将此数据放入System.Windows.Forms.RichTextBox的{{1}}然后读出其.Rtf值，我得到一个简单的转换。但是，它以某种方式带来了它的新线。

我尝试通过

删除它们

.Text

但它似乎没有帮助。

有谁知道如何将富文本格式转换为单行 纯文本？

看看这个example，提取的代码用于保存。

更新 - 从VB.NET程序中复制并粘贴错误 - 对不起大家。

class ConvertFromRTF
{
    static void Main()
    {

        string path = @"test.rtf";

        //Create the RichTextBox. (Requires a reference to System.Windows.Forms.dll.)
        using(System.Windows.Forms.RichTextBox rtBox = new System.Windows.Forms.RichTextBox());
        {

            // Get the contents of the RTF file. Note that when it is 
           // stored in the string, it is encoded as UTF-16. 
            string s = System.IO.File.ReadAllText(path);

            // Convert the RTF to plain text.
            rtBox.Rtf = s;
            string plainText = rtBox.Text;

            // Now just remove the new line constants
            plainText = plainText.Replace("\r\n", ",");

            // Output plain text to file, encoded as UTF-8.
            System.IO.File.WriteAllText(@"output.txt", plainText);
        }
    }
}

<强> How to: Convert RTF to Plain Text (C# Programming Guide)

在.NET Framework中，您可以使用RichTextBox控件创建支持RTF的文字处理程序，并允许用户以所见即所得的方式将格式应用于文本。

您还可以使用RichTextBox控件以编程方式从文档中删除RTF格式代码并将其转换为纯文本。您无需在Windows窗体中嵌入控件即可执行此类操作。
