C# 根据path递规创建文件夹

发布时间 2023-09-14 14:05:43作者: baivfhpwxf

使用场景很多，只要是要创建文件就要。所以写了一个。以后到处用就是了。

/// <summary>
/// 根据path递规创建文件夹
/// </summary>
/// <param name="filePath"></param>
/// <returns></returns>
public static bool CreateDirectoryByPath(this string filePath)
{
    var isOk = false;
    var filePathDirectory = filePath.Substring(0, filePath.LastIndexOf(@"\"));
    filePathDirectory = filePathDirectory.Replace("//", @"\").Replace("/", @"\");
    var directory = filePathDirectory.Split('\\').ToList();
    var existsDir = string.Empty;
    foreach (var item in directory)
    {
        existsDir += item + @"\";
        if (!Directory.Exists(existsDir))
        {
            Directory.CreateDirectory(existsDir);
        }
    }
    isOk = true;
    return isOk;
}

调用

//导出成文件
var filePath = AppContext.BaseDirectory + @"WeldResultUpload\" + DateTime.Now.ToString("yyyyMMdd") + @"\" + Global.WorkpieceTrayCode + ".xlsx";
if (filePath.CreateDirectoryByPath())
{
    FileHelper.Export(weldResultList.ToDataTable(), filePath);
    //数据文件路径
    Global.SecsServer.SetSvVal(10024, filePath);
}
