c# - 在c#中突出显示word文档中忽略大小写的文本

Question

使用以下代码可以突出显示搜索文本。但是，如果搜索文本是“也”，那么“也”不会突出显示。如何忽略案例。

 foreach (Word.Range w in doc.Words)
                            {

                                for (int i = 1; i < xmlnode.Count; i++)
                                {

                                    XmlAttributeCollection xmlattrc = xmlnode[i].Attributes;
                                    object text = xmlnode[i].FirstChild.InnerText;

                                    if (w.Text.Trim() == text.ToString())
                                    {
                                        w.Font.Bold = 1;
                                        w.HighlightColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkYellow;
                                    }
                                }
                            }
                        }

       // int counter = 0;
        object readOnly = true;
        System.IO.StreamReader file =
         new System.IO.StreamReader(@"C:\Users\noor\Desktop\HIGH LIGHTER\Sample.txt");
        object matchWholeWord = true;
        //string textToFind  = "to";
        //string my = System.IO.File.ReadAllText(@"C:\Users\noor\Desktop\HIGH LIGHTER\Sample.txt");
        //var textToFind = my ;
       // textBox1.Text = textToFind.ToString ();
        while ((line = file.ReadLine()) != null)
        {

            // Define an object to pass to the API for missing parameters
            object missing = System.Type.Missing;
            doc = word.Documents.Open(ref fileName,
                    ref missing, ref missing, ref missing, ref missing,
                    ref missing, ref missing, ref missing, ref missing,
                    ref missing, ref missing, ref missing, ref missing,
                    ref missing, ref missing, ref missing);
            string ReadValue = string.Empty;
            // Activate the document
            doc.Activate();

            /* foreach (Word.Range tmpRange in doc.StoryRanges)
             {
                 ReadValue += tmpRange.Text;
             }
         */
            foreach (Word.Range docRange in doc.Words)
                try
                {

                    if (docRange.Text.Trim().Equals(line, StringComparison.CurrentCulture) == false )
                    {
                        docRange.HighlightColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkYellow;
                        docRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdWhite;
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show("Error : " + ex.Message);
                }
        }
           // counter++;


        file.Close();

    }

您可能可以使用字符串比较方法：

if(String.Compare(w.Text.Trim(), text.ToString(), true) == 0)
