RunCmdBack——入参:certutil -hashfile c:\3d4596eb-6f99-4e9f-bb68-a8672cb5dd46.pdf md5
返回值:(注意,文件夹路径中文件夹名称不能存在空格)
使用方式如下所示:
private void btnGetHash_Click(object sender, EventArgs e) { string filePath = Application.StartupPath + "\\TestFile"; string cmd = "certutil -hashfile " + "测试.pdf" + " MD5";
//filePath = "D:\\测试 空格 文件夹"; var cmdFileHash = MD5Helper.Helper.MD5Helper.Instance.ExecuteOutCmd(cmd, filePath); this.txtCMDHash.Text = cmdFileHash; string runcmd = "certutil -hashfile " + Application.StartupPath + "\\TestFile\\测试.pdf" + " MD5"; this.txtCodeHash.Text = MD5Helper.Helper.MD5Helper.Instance.RunCmdBack(runcmd); }
运行效果如下所示:
ExecuteOutCmd 测试文件夹有空格的文件夹名称,如下所示:
