Windows -1252 不支持编码名称 [英] Windows -1252 is not supported encoding name

问题描述

我正在使用 Windows 10 通用应用程序和 ARM CPU 为 Raspberry Pi 创建应用程序.我收到以下编码错误:

I am working with windows 10 universal App and the ARM CPU to create apps for the Raspberry Pi. I get the following error with encoding:

附加信息:windows-1252"不是受支持的编码名称.有关定义自定义编码的信息，请参阅 Encoding.RegisterProvider 方法的文档.

Additional information: 'windows-1252' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.

 private async void Login(string passcode)
    {
        try
        {
            MySqlConnection conn = new MySqlConnection("Server=...");
            MySqlCommand cmd;

            conn.Open();

            cmd = new MySqlCommand("Select * from ...");

            var dr = cmd.ExecuteReader();

            int count = 0;

            while (dr.Read())
                count += 1;

            var dialog = new MessageDialog((count == 1) ? "Logged In" : "Error");
            await dialog.ShowAsync();

        }
        catch (Exception ex)
        {
           var dialog = new MessageDialog(ex.Message);
           await dialog.ShowAsync();
        }
        finally { conn.Close(); }
    }
}

我在这行代码中得到错误

I get the error in this line of code

dr = cmd.ExecuteReader();

在我习惯之前

conn.open();

但是我能够通过添加来解决它

But I was able to solve it by adding

charset=utf8

到连接字符串.

我该如何解决这个错误?

How can I solve this error?

推荐答案

从 .NET Core 2.2 项目中，我必须通过 Nuget 安装以下两个包:

From a .NET Core 2.2 project, I had to install via Nuget the following two packages:

(System.Text.Encoding & System.Text.Encoding.CodePages)

(System.Text.Encoding & System.Text.Encoding.CodePages)

那你必须在使用库之前进行设置:

Then you have to set it before the use of libraries:

 using System.Text;
 …
 {
    Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
    ...
 }
