# 场景 #

Winform中执行cmd命令的工具类，比如调用某些exe，类似mysqldump.exe这样类似的命令。

新建工具类CmdHelper

    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

调用示例

string cmdStr = mysqlDumpPath + " -h " + this.host.Text.Trim() + " -u" + this.username.Text.Trim() + " -p" + this.password.Text.Trim() + " " + this.database.Text.Trim() + " " + tableName + " > " + "\"" + this.textBox_bak_path.Text.Trim() + "\\" + tableName + ".sql\"";
                            CmdHelper.ExeCommand(cmdStr);
