C# Windows Mobile 6 System.PlatformNotSupportedException
我编写了一个小型WM 6.1应用程序,可以读取和写入xml,但我遇到了以下异常:C# Windows Mobile 6 System.PlatformNotSupportedException,c#,compact-framework,windows-mobile-6,C#,Compact Framework,Windows Mobile 6,我编写了一个小型WM 6.1应用程序,可以读取和写入xml,但我遇到了以下异常: System.PlatformNotSupportedException was unhandled Message="PlatformNotSupportedException" StackTrace: at System.Globalization.CompareInfo..ctor(Int32 culture) at System.Globalization.Compare

下面是CreatDT方法体:
public static DataTable CreateDT(string Setting, string Key, string Value)
{
DataTable dt;
dt = new DataTable(Setting);
dt.Columns.Add("Key", Type.GetType("System.String")); //<-- error here
dt.Columns.Add("Value", Type.GetType("System.String"));
AddRow(ref dt, Key, Value);
return dt;
}
publicstaticdatatable CreateDT(字符串设置、字符串键、字符串值)
{
数据表dt;
dt=新数据表(设置);
dt.Columns.Add(“Key”,Type.GetType(“System.String”);//如果它是PlatformNotSupportedException,那么问题取决于系统中不存在的功能。可能缺少一些Compact Framework组件
您可以尝试选择下面标记的选项(不幸的是,图片上没有选择),看看是否有帮助
无论Type.GetType(“System.String”)
是否会导致错误,我建议您在评论中使用Alex的typeof(String)
建议
话虽如此,请尝试在有问题的例程周围放置一个临时的try…catch块,以获得更详细的错误消息
public static DataTable CreateDT(string Setting, string Key, string Value)
{
DataTable dt = new DataTable(Setting);
try {
dt.Columns.Add("Key", typeof(String)); //<-- error here
dt.Columns.Add("Value", typeof("String"));
AddRow(ref dt, Key, Value);
} catch (Exception err) {
MessageBox.Show(err.Message);
if (err.InnerException != null) {
MessageBox.Show(err.InnerException.Message);
}
}
return dt;
}
publicstaticdatatable CreateDT(字符串设置、字符串键、字符串值)
{
DataTable dt=新的DataTable(设置);
试一试{
dt.Columns.Add(“Key”,typeof(String));//尝试用typeof(String)
替换Type.GetType(“System.String”)
(我没有任何方法测试代码,只是猜测)。typeof(String)
不起作用also@PawelZ此选项已选中
