经过大量研究,我找到了解决上述问题的方法。
通过使用类 ExeConfigurationFileMap 我们可以从 app.config 中获取键值,它无法绕过由混合模式组装错误导致的支持的运行时错误。
服务器 server = new Server(new ServerConnection(con)); server.ConnectionContext.ExecuteNonQuery(脚本);
该错误是在执行语句 ExecuteNonQuery 时引起的。
所以在执行语句之前
if(RuntimePolicyHelper.LegacyV2RuntimeEnabledSuccessfully)
server.ConnectionContext.ExecuteNonQuery(脚本);
解决方案如下
使用 System.Runtime.CompilerServices;
使用 System.Runtime.InteropServices;
公共静态类 RuntimePolicyHelper
{
公共静态布尔 LegacyV2RuntimeEnabledSuccessfully
{ 得到;私人套装; }
static RuntimePolicyHelper()
{
ICLRRuntimeInfo clrRuntimeInfo =
(ICLRRuntimeInfo)RuntimeEnvironment.GetRuntimeInterfaceAsObject(
Guid.Empty,
typeof(ICLRRuntimeInfo).GUID);
try
{
clrRuntimeInfo.BindAsLegacyV2Runtime();
LegacyV2RuntimeEnabledSuccessfully = true;
}
catch (COMException)
{
// This occurs with an HRESULT meaning
// "A different runtime was already bound to the legacy CLR version 2 activation policy."
LegacyV2RuntimeEnabledSuccessfully = false;
}
}
