如何在C＃中将char值分配给字符串变量

Question

i have a string strText with certain value on it,i need to assign '\\0' or charactor at the specified position of strText. ie strText[5]='\\0'.how is it possible in c#.

Answer 1

You can use the Insert method to specify the index. You need to give it a string though, so if you can replace '\\0' with "\\0" or else just call .ToString()

strText = strText.Insert(5, yourChar.ToString());

Answer 2

Strings are immutable, so you will need to convert it to a character array, set the character at the specified position, and then convert back to string:

char[] characters = "ABCDEFG".ToCharArray ();
characters[5] = '\0';
string foo = new String (characters);
