Go has several integer types: uint8, uint16, uint32, uint64, int8, int16, int32 and int64. But strconv only support 3 of them which is int, int64 and uint64. So let's see how to use it. Parse string to int func main() { res, err := strconv.Atoi("10") if err != n...
Type:string,Value:123 Go Copy strconv.FormatInt()函数 strconv包提供了另一个称为FormatInt()的函数,用于将整数变量转换为字符串。此函数需要两个参数:整数值和数字系统的基数。 示例 packagemainimport("fmt""strconv")funcmain(){num:=int64(123)str:=strconv.FormatInt(num,10)fmt.Printf("Type: %...

String Am = AmountTextBox.Text.ToString(); long l; Int64.TryParse(Am, out l); It will return false if the text can't be converted to long, so it's pretty safe to use. Otherwise, converting a long to int is a easy as int i = (int)yourLongValue; if you're happy with discar...
