Revit API 操作共享参数和项目参数

1.获取共享参数

 private string GetSharInfo(Autodesk.Revit.ApplicationServices.Application revitApp)
 {
     StringBuilder str = new StringBuilder();
     DefinitionFile definitionFile = revitApp.OpenSharedParameterFile();
     DefinitionGroups groups = definitionFile.Groups;
     foreach (DefinitionGroup group in groups)
     {
         foreach (Definition definition in group.Definitions)
         {
             string name = definition.Name;
             ParameterType type = definition.ParameterType;
             str.AppendLine(string.Format("{0}---{1}", name, type.ToString()));
         }
     }
     return str.ToString();
 }

2.创建共享参数

 private void CreateSharInfo(Autodesk.Revit.ApplicationServices.Application revitApp, Autodesk.Revit.DB.Document revitDoc)
 {
     try
     {
         string sharedParametersFilename = @"C:\shared-parameters.txt";
         string groupName = "MyGroup";
         string definitionName = "MyDefinition";
         ParameterType parameterType = ParameterType.Text;
         CategorySet categorySet = new CategorySet();
         Category wallCategory = revitDoc.Settings.Categories.get_Item(BuiltInCategory.OST_Walls);
         categorySet.Insert(wallCategory);
         bool instanceParameter = true;
         BuiltInParameterGroup parameterGroup = BuiltInParameterGroup.PG_DATA;
         if (!System.IO.File.Exists(sharedParametersFilename))
         {
             try
             {
                 System.IO.StreamWriter sw = System.IO.File.CreateText(sharedParametersFilename);
                 sw.Close();
             }
             catch (Exception)
             {
                 throw new Exception(string.Format("Can't create shared parameter file:{0}", sharedParametersFilename));
             }
         }
         revitApp.SharedParametersFilename = sharedParametersFilename;

         DefinitionFile definitionFile = revitApp.OpenSharedParameterFile();
         if (definitionFile == null)
         {
             throw new Exception("Can not open shared parameter file");
         }

         DefinitionGroups groups = definitionFile.Groups;
         DefinitionGroup group = groups.get_Item(groupName);
         if (group == null)
         {
             group = groups.Create(groupName);
         }
         Definition definition = group.Definitions.get_Item(definitionName);
         if (definition == null)
         {
             definition = group.Definitions.Create(new ExternalDefinitionCreationOptions(definitionName, parameterType));
         }
         ElementBinding binding = null;
         if (instanceParameter)
         {
             binding = revitApp.Create.NewInstanceBinding(categorySet);
         }
         else
         {
             binding = revitApp.Create.NewTypeBinding(categorySet);
         }
         bool insertSuccess = revitDoc.ParameterBindings.Insert(definition, binding, parameterGroup);
         if (!insertSuccess)
         {
             throw new Exception("Failed to bind definition to category");
         }
     }
     catch (Exception ex)
     {
         throw ex;
     }
 }

3.获取项目参数(API无法创建项目参数的)

 private string GetProjectParam(Autodesk.Revit.DB.Document revitDoc)
 {
     StringBuilder strBuild = new StringBuilder();
     BindingMap map = revitDoc.ParameterBindings;
     DefinitionBindingMapIterator dep = map.ForwardIterator();
     while (dep.MoveNext())
     {
         Definition definition = dep.Key;
         string definitionName = definition.Name;
         ParameterType parameterType = definition.ParameterType;
         InstanceBinding instanceBinding = dep.Current as InstanceBinding;
         if (instanceBinding != null)
         {
             CategorySet categorySet = instanceBinding.Categories;
             strBuild.AppendLine(string.Format("Name:{0} Type:{1} CategorySet:{2}", definitionName, parameterType, categorySet.GetType().ToString()));
         }
         else
         {
             strBuild.AppendLine(string.Format("Name:{0} Type:{1}", definitionName, parameterType));
         }
     }
     return strBuild.ToString();
 }

4.创建项目参数

Revit API无法创建项目参数，目前没有找到创建方法。
