Xamarin-找不到编码错误1252数据 [英] Xamarin - Encoding Error 1252 data could not be found

问题描述

我正在为 Visual Studio 2017 使用 Xamarin 中的应用程序.我正在尝试在 Android 和 iOS 实时播放器设备上测试我的应用程序.当我尝试运行它时，在我的设备( Android 和 iOS )上出现以下错误:

I am working on an application in Xamarin for Visual Studio 2017. I am attempting to test my application on Android and iOS live player devices. When I try to run it, I get the following error on my device (Android and iOS):

级别=错误，标题=可视化错误，消息=编码1252数据找不到.确保您具有正确的国际代码集程序集已安装并启用.(NotSupportedException)

Level=Error, Title=Visualization Error, Message=Encoding 1252 data could not be found. Make sure you have correct international codeset assembly installed and enabled. (NotSupportedException)

我通过 Google 搜索发现了类似的问题，但是进行更改后，它仍然无法运行.我已经检查了两个设备的所有国际化选项，甚至直接保存为 UTF-8 编码，因为我认为这可能是对 windows-1252 进行编码的问题.我还同时引用了 I18N.dll 和 I18N.West.dll .

I have found similar issues through Google searching, but after making the changes, it still will not run. I have checked all Internationalization options for both devices, and I have even saved directly as UTF-8 encoding, as I figured it may be an issue with encoding windows-1252. I also referenced the I18N.dll to the I18N.West.dll for both.

任何帮助将不胜感激.谢谢.

Any help would be greatly appreciated. Thank you.

更新:

我已经能够进一步缩小问题的范围.

I have been able to narrow down the issue further.

using (SqlConnection sqlConn = new 
 SqlConnection(Configuration.ConnectionString))
{
    //sqlConn.Open(); 
}

.open 导致编码错误.注释掉后，该应用程序将在实时设备上运行，但是，我现在得到:

The .open was causing the encoding error. After commenting it out, the app will run on the live device, however, I now get:

级别=错误，标题=未捕获的异常，消息=编码1252数据未找到.确保您已安装并启用了正确的国际代码集程序集.(NotSupportedException)

Level=Error, Title=Uncaught Exception, Message=Encoding 1252 data could not be found. Make sure you have correct international codeset assembly installed and enabled. (NotSupportedException)

Visual Studio 2017 会引发以下错误

System.Reflection.TargetInvocationException:调用的目标引发了异常.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

在

using (SqlConnection sqlConn = new 
SqlConnection(Configuration.ConnectionString))

它发生在它试图从上面的 using 语句中从数据库中提取的那一刻.我正在使用 SQL Server 2008 R2 .我只能说，使用 Android 和 iOS 向SQL Server发送和从SQL Server接收消息时遇到问题.

It occurs the moment it tries to pull from the database at the using statement above. I am using SQL Server 2008 R2. All I can tell is that it is having an issue with sending to and receiving from the SQL Server with Android and iOS.

更新2:

使用一些 Exception Handlers 之后，我将其归结为以下内部异常:

After using some Exception Handlers, I boiled it down to this inner exception:

哪个发生在:

DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);

推荐答案

在Visual Studio for Mac的"iOS Build"项目选项页中，应选中"west"复选框.Android属性相同.

From the "iOS Build" Project Options page in Visual Studio for Mac you should check "west" checkbox. Same for Android properties.

在Android项目中，转到属性"->"Android选项"

In the the Android project, go to Properties -> Android Options

然后使用链接器选项，在其他受支持的编码"中，选中西".

Then Linker Options, in the "Additional supported encodings" check "West".
