Question

How can I replace a char in a string with a string?

For Example:
Replace all char’s ‘e’ with “test”: “Hello World” -> “Htestllo World”.

A, string.replace(char,string), if you will.

Answer 1

// let's pretend this was a char that came to us from somewhere, already as a char...
char c = char.Parse("e");

// Here is the string we want to change...
string str1 = "Hello World."

// now we'll have to convert the char we have, to a string to perform the replace...
string charStr = c.ToString();

// now we can do the replace...
string str2 = str1.Replace(charStr,"test");
