Whenever you want to combine strings with some special characters, C# provides different ways to combine the strings for different symbols.
If you just want to add different string variables just use plus(+) operator to combine the strings as shown below.
string str1 = "This is One String ";
string str2 = "This is Second String ";
string str3 = str1 + str2;//str3 is result string
To Add the Tab character between strings use \t symbol while combining the strings as shown below.
string str1 = "This is One String \t";
string str2 = "This is Second String ";
string str3 = str1 + str2;//str3 is result string with tab character in between
To Add newline between strings use \n symbol between strings as shown below.
string str1 = "This is One String \n";
string str2 = "This is Second String ";
string str3 = str1 + str2;//str3 is result string with new character in between
To display the backslash in string use \\ symbol while adding two strings as shown below.
string str1 = "This is One String \\";
string str2 = "This is Second String ";
string str3 = str1 + str2;//str3 is result string with backslash character in between
To display the quotation in string use \" symbol in string as shown below.
string str1 = "This is One \"quoation\"";
string str2 = "This is Second String ";
string str3 = str1 + str2;//str3 is result string with quoation character in between
