访问路径被拒绝。 在 c#

Question

我正在使用 c# 编写应用程序，现在我在构建和写入 a.txt 文件时遇到了以下错误： Access to the path 'E:\compex\Thursday, October 10, 2019' is denied. 我的相关代码是：

 private void creat_Click(object sender, EventArgs e)
    {
        string filename = "E:\\compex\\"+DateTime.Now.ToLongDateString() ;
        string msadd = filename + "\\msadd.txt";
        textpatch.Text = msadd;
        Directory.CreateDirectory(filename);
        filepatch.Text =  filename;
        using(FileStream fp = File.Create(filename))
        {
            log.Text = "address file created successfully";
            Byte[] filepatchs = new UTF8Encoding(true).GetBytes(filename);
            fp.Write(filepatchs, 0, filepatchs.Length);
            log.Text = "";
            log.Text = "address  successfully";
        } 



    }

它出什么问题了？ windows 中是否有任何权限或用于获得该权限的代码？

private void creat_Click(object sender, EventArgs e)
{
        string filename = "E:\\compex\\"+DateTime.Now.ToLongDateString() ;
        string msadd = filename + "\\msadd.txt";
        textpatch.Text = msadd;
        Directory.CreateDirectory(filename);
        filepatch.Text =  filename;
        using(FileStream fp = File.Create(msadd))
        {
            log.Text = "address file created successfully";
            Byte[] filepatchs = new UTF8Encoding(true).GetBytes(filename);
            fp.Write(filepatchs, 0, filepatchs.Length);
            log.Text = "";
            log.Text = "address  successfully";
        } 



}

我相信，根据您的评论回复，您打算使用msadd作为要在using块中写入的串联文件名，而不是使用为目录和文件filename重复的文件名。
