从PowerDesigner表字段的Name到EF实体类属性的Display Name(根据PowerDesigner生成EF实体类中文注释和验证元数据)

第一步:将PowerDesigner表字段的中文Name填入Comment中:工具-Execute Commands-Edit/Run Script...

(可保存为文件以后直接打开执行)

 

第二步:从PowerDesigner表字段的Comment到SQL Server表字段的MS_Description(说明):数据库-Generate Database...

 

第三步:创建EF edmx文件

 

第四步:将SQL Server表字段的MS_Description(说明)添加到EF edmx文件:

EFTSQLDocumentation.Generator.exe -c "Data Source=.;Initial Catalog=xxxdb;User ID=sa;Password=yyy;" -i "上一步生成的edmx文件的完整路径"

然后刷新edmx(从数据库更新模型),可以多刷两遍。

(EFTSQLDocumentation.Generator.exe可到https://eftsqldocgenerator.codeplex.com/下载)

 

最后一步:修改生成实体类的T4模板(默认叫Model1.tt):

Model1.tt Namespace段:

public void BeginNamespace(CodeGenerationTools code){  var codeNamespace = code.VsNamespaceSuggestion();  if (!String.IsNullOrEmpty(codeNamespace))  {#>namespace Models{  using System.ComponentModel.DataAnnotations;<#+    PushIndent("  ");  }}public void EndNamespace(CodeGenerationTools code){  if (!String.IsNullOrEmpty(code.VsNamespaceSuggestion()))  {    PopIndent();#>}<#+  }}

  public string Property(EdmProperty edmProperty)  {    string doc = "";    if (edmProperty.Documentation != null)    {      doc = string.Format(      CultureInfo.InvariantCulture,      "\n\t\t/// <summary>\n\t\t/// {0} - {1}\n\t\t/// </summary>\n\t\t",      edmProperty.Documentation.Summary ?? "",      edmProperty.Documentation.LongDescription ?? "");      doc += string.Format(      CultureInfo.InvariantCulture,      "[Display(Name = \"{0}\")]\n\t\t",      edmProperty.Documentation.Summary.Replace('(', '_').Replace(')', '_').Replace('(', '_').Replace(')', '_').Replace(" ", "") ?? "",      edmProperty.Documentation.LongDescription ?? "");    }    if (!edmProperty.Nullable)    {      doc += "[Required(ErrorMessage = \"您需要填写{0}!\")]\n\t\t";    }    var maxLengthFacet = (Facet)edmProperty.TypeUsage.Facets.SingleOrDefault(f => f.Name == "MaxLength");    if(maxLengthFacet != null && !maxLengthFacet.IsUnbounded)    {      doc += "[StringLength("+ maxLengthFacet.Value +", ErrorMessage = \"{0}长度不能超过"+ maxLengthFacet.Value +"\")]\n\t\t";    }    return doc + string.Format(      CultureInfo.InvariantCulture,      "{0} {1} {2} {{ {3}get; {4}set; }}",      Accessibility.ForProperty(edmProperty),      _typeMapper.GetTypeName(edmProperty.TypeUsage),      _code.Escape(edmProperty),      _code.SpaceAfter(Accessibility.ForGetter(edmProperty)),      _code.SpaceAfter(Accessibility.ForSetter(edmProperty)));  }  public string NavigationProperty(NavigationProperty navigationProperty)  {    var endType = _typeMapper.GetTypeName(navigationProperty.ToEndMember.GetEntityType());    string doc = "";    if (navigationProperty.Documentation != null)    {      doc = string.Format(      CultureInfo.InvariantCulture,      "\n\t\t/// <summary>\n\t\t/// {0} - {1}\n\t\t/// </summary>\n\t\t",      navigationProperty.Documentation.Summary ?? "",      navigationProperty.Documentation.LongDescription ?? "");    }    return doc + string.Format(      CultureInfo.InvariantCulture,      "{0} {1} {2} {{ {3}get; {4}set; }}",      AccessibilityAndVirtual(Accessibility.ForProperty(navigationProperty)),      navigationProperty.ToEndMember.RelationshipMultiplicity == RelationshipMultiplicity.Many ? ("ICollection<" + endType + ">") : endType,      _code.Escape(navigationProperty),      _code.SpaceAfter(Accessibility.ForGetter(navigationProperty)),      _code.SpaceAfter(Accessibility.ForSetter(navigationProperty)));  }

Model1.tt Property段
