我必須簡短這個方法public dataconnect [] GetData（string strLevelName）itryed從新函數調用數據，但它不工作..任何人都幫助我！請

你說的意思是什麼？「我必須總之這個方法」？你想達到什麼目的？ – mdm 2012-03-30 10:21:46

很難從你的描述中知道什麼是問題。你能提供更多的信息，比如錯誤信息嗎？ – mortb 2012-03-30 10:23:51

'GetData'方法似乎已經爲某些重構做好了準備... – 2012-03-30 10:24:01

這是很難理解你的問題，但我懷疑你正在嘗試返回一個比當前傳輸綁定設置所允許的數組大的數組。
BOTH在您的服務器和客戶端，你應該看看增加您的readerQuotas例如：

<readerQuotas maxDepth="32" 
       maxStringContentLength="10000000" maxArrayLength="10000000" 
       maxBytesPerRead="10000000" maxNameTableCharCount="10000000" />

，可能也是你的緩衝區大小：

maxBufferPoolSize="10000000" 
maxBufferSize="10000000" 
maxReceivedMessageSize="10000000">

你應該重新您的因子模型DataContract

[DataContract] 
public class Store 
{ 
    [DataMember] 
    public string TpoStoreid {get; set;} 

    [DataMember] 
    public Region {get; set;} 

    //more properties.. 
} 

[DataContract] 
public class Region 
{ 
    [DataMember] 
    public string TpoRegionId {get; set;} 

    [DataMember] 
    public Account {get; set;} 

    //more properties.. 
} 

[DataContract] 
public class Account { 
    //..... 
}

從單一職責原則的功能應該做的一兩件事。

你的函數做了什麼..

從數據庫中獲取存儲（包括相關數據）的記錄。
創建映射每個記錄的字段的新對象。

所以，你可以分離私人方法有關MySQL查詢從DataReader的

private Store ReadStore(SqlDataReader dr) 
{ 
    var store = new Store(); 
    store.TpoStoreId = dr[0]; 
    //set more properties... 

    return store; 
}

讀取數據，你應該加入表instead.try谷歌關於MySQL JOIN表
