C#在word文檔中替換字符串

在文檔中搜索和替換字符串,先在word文檔中標記字符串,然後再搜索標記字符串並用新的字符串替換標記字符串.主要是先選擇整個文檔,然後使用Find的Execute方法查找指定字符串並替換爲相應字符串.

以下實現方式之一,使用文檔(Document )對象的 Content 屬性選擇整個文檔。

///<summary>
                /// 在word 中查找一個字符串直接替換所需要的文本
                /// </summary>
                /// <param name="strOldText">原文本</param>
                /// <param name="strNewText">新文本</param>
                /// <returns></returns>
                public bool Replace(string strOldText,string strNewText)
                {
                        this.oDoc.Content.Find.Text = strOldText ;
                        object FindText,    ReplaceWith, Replace ;//    
                        object MissingValue = Type.Missing;    
                        FindText = strOldText ;//要查找的文本
                        ReplaceWith = strNewText ;//替換文本
                             Replace = Word.WdReplace.wdReplaceAll ;/**//*wdReplaceAll - 替換找到的所有項。
                                                                                                            * wdReplaceNone - 不替換找到的任何項。
                                                                                                        * wdReplaceOne - 替換找到的第一項。
                                                                                                        * */
                        this.oDoc.Content.Find.ClearFormatting();//移除Find的搜索文本和段落格式設置
                        if (this.oDoc.Content.Find.Execute(
                                ref FindText,ref MissingValue,
                                ref MissingValue,ref MissingValue,
                                ref MissingValue,ref MissingValue,
                                ref MissingValue,ref MissingValue,ref MissingValue,
                                ref ReplaceWith,ref Replace,
                                ref MissingValue,ref MissingValue,
                                ref MissingValue,ref MissingValue))
                        {
                                return true ;
                        }
                        return false ;
                        
                }

 

說明:其中oDoc是一個word文檔的Document對象.

 

此外還可以 運用Word Application 對象Selection的Find.

public bool SearchReplace(string strOldText,string strNewText)
                {    
                        object replaceAll = Word.WdReplace.wdReplaceAll;    
                        object missing = Type.Missing;    
                        
                                //首先清除任何現有的格式設置選項，然後設置搜索字符串 strOldText。
                        this.oWordApplic.Selection.Find.ClearFormatting();    
                        oWordApplic.Selection.Find.Text = strOldText;    

                        oWordApplic.Selection.Find.Replacement.ClearFormatting();    
                        oWordApplic.Selection.Find.Replacement.Text = strNewText;    

                        if (oWordApplic.Selection.Find.Execute(
                                ref missing, ref missing, ref missing, ref missing, ref missing,    
                                ref missing, ref missing, ref missing, ref missing, ref missing,
                                ref replaceAll, ref missing, ref missing, ref missing, ref missing))
                        {
                                return true ;
                        }
                        return false ;
                }

注:oWordApplic是一個Word Application 對象
