Golang为CMD执行cd命令

I want to use golang and exec library to go to a certain path "c:\" and run a .exe file.

when i run my go code it gives me:

exec: "cd:/": file does not exist

cdcdDirCmd

package main

import (
    "fmt"
    "log"
    "os/exec"
)

func main() {
    cmd := exec.Command("program") // or whatever the program is
    cmd.Dir = "C:/usr/bin"         // or whatever directory it's in
    out, err := cmd.Output()
    if err != nil {
        log.Fatal(err)
    } else {
        fmt.Printf("%s", out);
    }
}

See the Cmd documentation for more information. Alternatively, you could use os/Chdir to change the working directory before running the program.
