C#数值格式
示例
//整数类型为十六进制 string.Format("Hexadecimal: byte2: {0:x2}; byte4: {0:X4}; char: {1:x2}", 123, (int)'A'); //带有千位分隔符的整数 string.Format("Integer, thousand sep.: {0:#,#}; fixed length: >{0,10:#,#}<", 1234567); //带有前导零的整数 string.Format("Integer, leading zeroes: {0:00}; ", 1); //小数点 string.Format("Decimal, fixed precision: {0:0.000}; as percents: {0:0.00%}", 0.12);
输出:
Hexadecimal: byte2: 7b; byte4: 007B; char: 41 Integer, thousand sep.: 1,234,567; fixed length: > 1,234,567< Integer, leading zeroes: 01; Decimal, fixed precision: 0.120; as percents: 12.00%
