CS0029 C＃'无法将类型字符串[]隐式转换为字符串'

I'm making an application to edit the properties of .mp3 files. I have to say I'm pretty new to programming and *, so I might be doing something very obviously wrong. Please forgive me! This is the code I am using:

我正在创建一个应用程序来编辑.mp3文件的属性。我不得不说我对编程和*很新，所以我可能会做一些非常明显错误的事情。请原谅我！这是我正在使用的代码：

private void btnApply_Click(object sender, EventArgs e)
{
    var file = TagLib.File.Create(filepath);
    if (!string.IsNullOrWhiteSpace(txtGenre.Text))
    {
        file.Tag.Genres = new string[] {txtGenre.Text};
    }
    if (!string.IsNullOrWhiteSpace(txtArtist.Text))
    {
        file.Tag.Performers = new string[] {txtArtist.Text};
    }
    if (!string.IsNullOrWhiteSpace(txtTitle.Text))
    {
        file.Tag.Title = new string[] {txtTitle.Text};
    }
    file.Tag.Performers = new string[] { txtArtist.Text };
    file.Tag.Title = txtTitle.Text;
    file.Save();

    if (!ReadFile())
    {
        Close();
    }
}

The odd thing to me is that I only get an error for this part:

对我来说奇怪的是我只得到这个部分的错误：

if (!string.IsNullOrWhiteSpace(txtTitle.Text))
{
    file.Tag.Title = new string[] {txtTitle.Text};
}

With this being underlined red:

这有红色下划线：

new string[] {txtTitle.Text}

What am I missing here? I've been looking for a very long time but I just can't seem to find any solutions. Thank you in advance! I am also using TagLib, by the way.

我在这里想念的是什么？我一直在寻找很长一段时间，但我似乎无法找到任何解决方案。先谢谢你！顺便说一句，我也在使用TagLib。

2 个解决方案

#1

Change this:

改变这个：

file.Tag.Title = new string[] {txtTitle.Text};

to:

至：

file.Tag.Title = txtTitle.Text;

Title type is string, not array of strings (not string[]), but you try to assign array - because of it you get error. Other fields have type string[] (array of strings), that's why you get error only with Title.

标题类型是字符串，而不是字符串数组（不是string []），但是您尝试分配数组 - 因为它会导致错误。其他字段的类型为string []（字符串数组），这就是为什么只有Title才会出错。

Also, you try to assign value to Title 2 times:

此外，您尝试将值分配给标题2次：

if (!string.IsNullOrWhiteSpace(txtTitle.Text))
{
    file.Tag.Title = new string[] {txtTitle.Text};    // first time
}
file.Tag.Performers = new string[] { txtArtist.Text };
file.Tag.Title = txtTitle.Text;                       //second time

You need to assign only one time. Also, when you assign second time you assign it correctly without error.

您只需要分配一次。此外，当您第二次分配时，您可以正确分配它而不会出错。

The same situation with Performers - you assign first time inside if statement and second time after the last if.

与表演者相同的情况 - 你在if语句中分配第一次，在最后一次if之后第二次分配。

Change the code like this and try

像这样更改代码并尝试

file.Tag.Title = txtTitle.Text;
