ArcEngine将对象存储到Blob字段中！

在Geodatabase中有一张Table，希望通过AE开发的方式将信息存储到表的一个Blob字段中。这个该如何实现？

 1  IWorkspaceName pWpsName = null; //当前工作空间名称
 2             pWpsName= GWorkSapce.CreateAccessWorkSpace();
 3             if (pWpsName==null)
 4             {
 5                 return;
 6             }
 7             m_WorkspacePath = pWpsName.PathName;
 8             IWorkspaceFactory pWspFactory = pWpsName.WorkspaceFactory;
 9             IWorkspace pWsp = pWspFactory.OpenFromFile(m_WorkspacePath, 0);
10             IFeatureWorkspace pFeatWsp = pWsp as IFeatureWorkspace;
11 
12             IFieldInfo m_fieldOID=new OIDField();
13 
14             IFieldInfo m_field1=new TableField();
15             m_field1.Name_2="Item";
16             m_field1.AliasName_2="Item";
17             m_field1.Type_2=esriFieldType.esriFieldTypeString;
18             m_field1.Length_2 = 64;
19 
20             IFieldInfo m_field2 = new TableField();
21             m_field2.Name_2 = "Value_1";
22             m_field2.AliasName_2 = "Value_1";
23             m_field2.Type_2 = esriFieldType.esriFieldTypeBlob;  
24         
25             IList<IFieldInfo> listField = new List<IFieldInfo>();
26             listField.Add(m_fieldOID);
27             listField.Add(m_field1);
28             listField.Add(m_field2);
29             GFieldsInfo gFieldsInfo=new GFieldsInfo(listField);
30             
31             IFields m_fields=gFieldsInfo.CreateFieldsForTable();
32 
33             IObjectClass m_InfoObj=GWorkSapce.CreateObjectClass(pWsp, "Info", m_fields);
34             IRow row1=((ITable)m_InfoObj).CreateRow();
35             var Itemindex = m_InfoObj.Fields.FindField("Item");
36             row1.set_Value(Itemindex, "空间参考");
37             byte[] byteArray = {1, 2, 3};
38             MemoryBlobStream blob = new MemoryBlobStream();
39             ((IMemoryBlobStreamVariant)blob).ImportFromVariant(byteArray as object);//将一个Byte[]对象作为参数传入
40             var index = m_InfoObj.Fields.FindField("Value_1");
41             IField field = m_InfoObj.Fields.get_Field(index);
42             if (field.CheckValue(blob))
43             {
44                 row1.set_Value(index, blob);
45             }
46             row1.Store();
47             IRow test = ((ITable)m_InfoObj).GetRow(1);
48             object objtest=test.get_Value(2);
49             IMemoryBlobStreamVariant pVar = objtest as IMemoryBlobStreamVariant;
50             object pobj = new object();
51             pVar.ExportToVariant(out pobj); //转入Object对象
52             MessageBox.Show(((byte[])pobj)[1].ToString());
