用新值替换旧值到字符串中

问题描述

在我的字符串变量中，此代码存储&我想将此字符串

in my string variable this code is stored & I want to replace this string

this.Name = "rptTableReport1"

替换为

this.Watermark.Text = "Trial version";

字符串变量数据

string variable data

string Reportsetting=this.Bands.AddRange(new DevExpress.XtraReports.UI.Band[] {
                       this.Detail,
                       this.TopMargin,
                       this.BottomMargin});
           this.Margins = new System.Drawing.Printing.Margins(0, 100, 100, 42);
           this.Name = "rptTableReport1";
           this.PageHeight = 1100;
           this.PageWidth = 850;
           this.TextAlignment = DevExpress.XtraPrinting.TextAlignment.TopJustify;
           this.Version = "11.1";
           this.Watermark.Text="ABC"
           this.Watermark.Font = new System.Drawing.Font("Verdana", 40F);
           this.Watermark.ForeColor = System.Drawing.Color.DodgerBlue;
           this.Watermark.ShowBehind = false;
           this.Watermark.TextTransparency = 170;
           ((System.ComponentModel.ISupportInitialize)(this)).EndInit();

我使用了以下编码

i have used the following coding

string oldSTR = @"            this.Name = ""rptTableReport1""; ";
 string newSTR = @"             this.Watermark.Text = ""TRIAL VERSION"";";
 Reportsetting.Replace(oldSTR, newSTR);

但不会替换字符串
请告诉正确的方法替换此字符串.

在字符串变量中，我已经有this.Watermark.Text ="VALUE"&我要替换此值如何替换此值?

在此先感谢..

but it will not replace the string
please tell right method to replace this string.

in string variable i have already this.Watermark.Text =" VALUE" & i want to replace this value how to replace this value?

thanks in advance..

推荐答案

string oldSTR = @"this.Name = ""rptTableReport1"";";
 string newSTR = @"this.Watermark.Text = ""TRIAL VERSION"";";
 Reportsetting.Replace(oldSTR, newSTR);
