Static void Main (string [] args) {string str1 = 12345. toString ("n"); Console. writeLine ("12345. toString (\ "n \") = {0} ", str1); string str2 = 12345. toString ("c"); Console. writeLine ("12345. toString (\ "c \") = {0} ", str2); string str3 = 12345. toString ("f4"); Console. writeLine ("12345. toString (\ "f4 \") = {0} ", str3); string str4 = 12345. toString ("p"); Console. writeLine ("12345. toString (\ "p \") = {0} ", str4); string str5 = 12345. toString ("#,## 0.00"); Console. writeLine ("12345. toString (\ "#,## 0.00 \") = {0} ", str5); Console. readKey ();}
