突出显示文本忽略 C# 中 Word 文档中的大小写

使用以下代码，我能够突出显示搜索文本。但是，如果搜索文本是"也"，则"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");

        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,

            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 Compare 方法：

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