Es wäre wirklich nett, wenn Microsoft Parameternamen, zumindest auf einer Kontextbasis, einzigartig machen würde.
Ich habe ein Problem für diese here erstellt.
In der Zwischenzeit konnte ich dies durch Tweaking einiger Funktionen in der .Context.tt Datei zur Arbeit kommen, so dass es eine GUID zu jedem Parameternamen zur Laufzeit ergänzt:
private void WriteFunctionImport(TypeMapper typeMapper, CodeStringGenerator codeStringGenerator, EdmFunction edmFunction, string modelNamespace, bool includeMergeOption) {
if (typeMapper.IsComposable(edmFunction))
{
#>
[EdmFunction("<#=edmFunction.NamespaceName#>", "<#=edmFunction.Name#>")]
<#=codeStringGenerator.ComposableFunctionMethod(edmFunction, modelNamespace)#>
{ var guid = Guid.NewGuid().ToString("N"); <#+
codeStringGenerator.WriteFunctionParameters(edmFunction, " + guid", WriteFunctionParameter);
#>
<#=codeStringGenerator.ComposableCreateQuery(edmFunction, modelNamespace)#>
} <#+
}
else
{
#>
<#=codeStringGenerator.FunctionMethod(edmFunction, modelNamespace, includeMergeOption)#>
{ <#+
codeStringGenerator.WriteFunctionParameters(edmFunction, "", WriteFunctionParameter);
#>
<#=codeStringGenerator.ExecuteFunction(edmFunction, modelNamespace, includeMergeOption)#>
} <#+
if (typeMapper.GenerateMergeOptionFunction(edmFunction, includeMergeOption))
{
WriteFunctionImport(typeMapper, codeStringGenerator, edmFunction, modelNamespace, includeMergeOption: true);
}
} }
. ..
public void WriteFunctionParameters(EdmFunction edmFunction, string nameSuffix, Action<string, string, string, string> writeParameter)
{
var parameters = FunctionImportParameter.Create(edmFunction.Parameters, _code, _ef);
foreach (var parameter in parameters.Where(p => p.NeedsLocalVariable))
{
var isNotNull = parameter.IsNullableOfT ? parameter.FunctionParameterName + ".HasValue" : parameter.FunctionParameterName + " != null";
var notNullInit = "new ObjectParameter(\"" + parameter.EsqlParameterName + "\"" + nameSuffix + ", " + parameter.FunctionParameterName + ")";
var nullInit = "new ObjectParameter(\"" + parameter.EsqlParameterName + "\"" + nameSuffix + ", typeof(" + parameter.RawClrTypeName + "))";
writeParameter(parameter.LocalVariableName, isNotNull, notNullInit, nullInit);
}
}
...
public string ComposableCreateQuery(EdmFunction edmFunction, string modelNamespace)
{
var parameters = _typeMapper.GetParameters(edmFunction);
return string.Format(
CultureInfo.InvariantCulture,
"return ((IObjectContextAdapter)this).ObjectContext.CreateQuery<{0}>(\"[{1}].[{2}]({3})\"{4});",
_typeMapper.GetTypeName(_typeMapper.GetReturnType(edmFunction), modelNamespace),
edmFunction.NamespaceName,
edmFunction.Name,
string.Join(", ", parameters.Select(p => "@" + p.EsqlParameterName + "\" + guid + \"").ToArray()),
_code.StringBefore(", ", string.Join(", ", parameters.Select(p => p.ExecuteParameterName).ToArray())));
