使用 C# 代碼從 DYNAMICS 365 crm 檢索/獲取記錄

Question

• 問題1：

  我是 MICROSOFT DYNAMICS CRM 365 的新手。我的 CRM 表很少，例如（帳戶，客戶）。我想從表帳戶中獲取所有數據。

以下是我的連接示例代碼：（不確定這是否正確，但收到我已連接到 CRM 的輸出消息）

public void ConnectToMSCRM(string UserName, string Password, string SoapOrgServiceUri)  
    {  
        try  
        {  
            ClientCredentials credentials = new ClientCredentials();  
            credentials.UserName.UserName = UserName;  
            credentials.UserName.Password = Password;  
            Uri serviceUri = new Uri(SoapOrgServiceUri);  
            OrganizationServiceProxy proxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);  
            proxy.EnableProxyTypes();  
            _services = (IOrganizationService)proxy;  
            Response.Write("Connected to CRM \n");  
}  

我需要在按鈕單擊事件上檢索所有數據。
輸出應該是： "select * from ABC" ；

• 問題2：

如果可能，請建議如何使用給定的列名獲取記錄。
輸出應該是： "select * from ABC where ColumnName="test" ；

Answer 1

將所有實體列表提取到列表中

    var allEntities = **GetEntities(_service);**
    foreach (var Entity in allEntities)
    {
        ddlEntityName.Items.Add(Entity.LogicalName);
    }

//單參數函數（oganizationservice作為參數）

//這將從 Microsoft Dynamics CRM 中獲取表/實體名稱，如 ACCOUNT、CONTACT

public Microsoft.Xrm.Sdk.Metadata.EntityMetadata[] GetEntities(IOrganizationService organizationService)
    {
        Dictionary<string, string> attributesData = new Dictionary<string, string>();
        RetrieveAllEntitiesRequest metaDataRequest = new RetrieveAllEntitiesRequest();
        RetrieveAllEntitiesResponse metaDataResponse = new RetrieveAllEntitiesResponse();
        metaDataRequest.EntityFilters = EntityFilters.Entity;

        XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
        myReaderQuotas.MaxNameTableCharCount = 2147483647;

        // Execute the request.

        metaDataResponse = (RetrieveAllEntitiesResponse)organizationService.Execute(metaDataRequest);

        var entities = metaDataResponse.EntityMetadata;

        return entities.OrderBy(x => x.LogicalName).ToArray();//to arrange in ascending order
    }

Answer 2

查詢表達式呢？

這是您的查詢：

Select * from ABC where ColumnName="test";

這是QueryExpression ：

QueryExpression query = new QueryExpression()
{
    EntityName = Contact.EntityLogicalName,
    ColumnSet = new ColumnSet("address1_telephone1"),
};

執行查詢，這是如何：

DataCollection<Entity> entityCollection = _services.RetrieveMultiple(query).Entities;

// Display the results.
foreach (Contact entity in entityCollection)
{
    Console.WriteLine("my test: {0}", entity.address1_telephone1);
}
