抽空研究了下API，目前1.4版本，还不错。
记录下

demo代码如下
string db = @"Z:dataDK.gdb";
Geodatabase geodatabase = Geodatabase.Open(@"Z:dataDK.gdb");
string[] pArrayDST = geodatabase.DataSetTypes;
string[] pArrayDRT = geodatabase.DatasetRelationshipTypes;
string[] pArrayFC = geodatabase.GetChildDatasets("\", "Feature Class");
string[] pArrayFD = geodatabase.GetChildDatasets("\", "Feature Dataset");
string[] pArrayFC2 = geodatabase.GetChildDatasets(pArrayFD[0], "Feature Class");
目前，对于字段别名有点问题，FieldDefs始终为null，至于FieldInformation中，没有字段别名。估计是漏掉了？
这个问题倒是好解决，做一张字段对照表，导出的时候就可以了。
看demo会发现，似乎esri对这个api采用的是py的路子，通过字符串进行识别，把gdb当作文件夹来操作。
而且对于创建表之类的采用了xml思路，如果不是偷懒，就是为了跨平台。
