读取文本文件并进行更改c＃

Question

i want to read a text file that Contains

<CustomerName>@CoustomerName</CoustomerName>
<CustomerAddress>@CustomerAddress</CustomerAddress>
<CustomerMobileNo>@CustomerMobileNo</CustomerMobileNo>
<Payment>@Payment</Payment>

Replace this @CoustomerName with Coustomer Name Passes During Run Time

Till then i use this

string readfile = File.ReadAllText(path);
Regex.Replace(readfile , "@CoustomerName ", objProposar.FirstName);

This works But i need to make changes in Coustomer address, mobile no etc How can i do this

Answer 1

Why regex, a simple String.Replace will do the job:

string oldText = File.ReadAllText(path);
string newText = oldText.Replace("@CoustomerName", objProposar.FirstName);
// other ...
File.WriteAllText(path, newText);

Answer 2

If your file is XML - use XML way of doing it, like XDocument, otherwise string.Replace is a better option:

string readfile = File.ReadAllText(path);
readfile = readfile.Replace("@CoustomerName", objProposar.FirstName);
