Question

我使用Sync框架编写了一个包装器来提供通用功能。

这是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Synchronization.Data;
using Microsoft.Synchronization.Data.SqlServer;
using System.Data.SqlClient;
using Microsoft.Synchronization;


namespace PluginTest.Components
{
    public class P2PProvsionProvider
    {
        public SqlConnection RemoteConnection { get; set; }
        public SqlConnection LocalConnection { get; set; }
        private static Dictionary<string,DbSyncScopeDescription> scopes { get; set; }
        private static SqlSyncScopeProvisioning remoteProvision { get; set; }
        private static SqlSyncScopeProvisioning localProvision { get; set; }

        private static P2PProvsionProvider provider;

        //private P2PProvsionProvider() { 
        //}

        public P2PProvsionProvider() {
            scopes = new Dictionary<string, DbSyncScopeDescription>();
        }

        public static P2PProvsionProvider getInstance(string name) {
            if (name.Equals("default"))
                if (provider == null)
                    provider = new P2PProvsionProvider();
            return provider;
        }
        //1
        public void CreateProvisionScope(string name) {
            if (!scopes.ContainsKey(name))
            {
                scopes.Add(name, new DbSyncScopeDescription(name));
            }
        }

        //2
        public void AddProvisionTable(string scopeName, string tableName) {

            if (scopes[scopeName] != null)
            {
                DbSyncScopeDescription remoteScopeDesc = scopes[scopeName];
                //DbSyncScopeDescription localScopeDesc = scopes[scopeName];
                DbSyncTableDescription remoteTableDesc = SqlSyncDescriptionBuilder.GetDescriptionForTable(tableName, RemoteConnection);
                //DbSyncTableDescription localTableDesc = SqlSyncDescriptionBuilder.GetDescriptionForTable(tableName, LocalConnection);

                remoteScopeDesc.Tables.Add(remoteTableDesc);
                //localScopeDesc.Tables.Add(localTableDesc);

            }
        }

        //3
        public void ApplyScopeProvisioning (string scopeName){

            remoteProvision = new SqlSyncScopeProvisioning(RemoteConnection, scopes[scopeName]);
            remoteProvision.SetCreateProceduresDefault(DbSyncCreationOption.Skip);
            remoteProvision.Apply();

            localProvision = new SqlSyncScopeProvisioning(LocalConnection, scopes[scopeName]);
            localProvision.SetCreateProceduresDefault(DbSyncCreationOption.Skip);
            localProvision.Apply(); 

        }

            return remoteProvision;

            SyncOrchestrator syncOrachestrator = new SyncOrchestrator() {
                LocalProvider = new SqlSyncProvider(scopeName, LocalConnection),
                RemoteProvider = new SqlSyncProvider(scopeName, RemoteConnection), 
                Direction = direction 
            };

            ((SqlSyncProvider)syncOrachestrator.LocalProvider).ApplyChangeFailed += (s,e) =>
            {

            };

            return syncOrachestrator.Synchronize();
        }

        //5 Deprovision certain scope
        public void DeprovisionScope(SqlConnection conn, string scopeName) {
            SqlSyncScopeDeprovisioning deprovisionScope = new SqlSyncScopeDeprovisioning(conn);
            deprovisionScope.DeprovisionScope(scopeName);
        }

        //6 Deprovision All
        public void DeprovisionStore(SqlConnection conn)

            SqlSyncScopeDeprovisioning deprovisionScope = new SqlSyncScopeDeprovisioning(conn);
            deprovisionScope.DeprovisionStore();
        }
    }
}

正如问题所示，我得到一个InvalidOperationException，表示说某些存储过程不存在。该应用程序如下工作：在表格

中提供了以下定义

    public GlobalFramework.Core core { get; set; }
    public BindingList<string> addedTables { get; set; }
    public BindingList<string> provisionedTables { get; set; }
    public P2PProvsionProvider provider { get; set; }
    public SyncOperationStatistics stats { get; set; }

1-当用户点击带有“添加配置范围”文本的按钮时，将完成以下操作：

private void provisionButton_Click(object sender, EventArgs e)
    {
        provider.CreateProvisionScope(provisionScopeTextBox.Text);
        foreach (var item in provisionedTables)
        {
            provider.AddProvisionTable(provisionScopeTextBox.Text, item);
        }

    }

2-当用户点击带有“Apply Provision”的按钮时，完成以下操作

private void applyProvisionButton_Click(object sender, EventArgs e)
    {
        provider.ApplyScopeProvisioning(provisionScopeTextBox.Text);
    }

3-当用户点击“同步”按钮时，完成以下操作

private void syncButton_Click(object sender, EventArgs e)
    {
        stats = provider.ExecuteSync(provisionScopeTextBox.Text);
        statsLabel.Text = "Start time: " + stats.SyncStartTime + "End Time: " +stats.SyncEndTime+ "Change Total: "+stats.DownloadChangesTotal; 
    }

现在我想知道为什么我一直得到这个例外？我的本地数据库连接是SQL Server 2008 R2。我的远程数据库也是SQL Server 2008 R2。

P.S：我知道我应该只规定一次范围。

Answer 1

为什么要跳过存储过程的创建？

remoteProvision.SetCreateProceduresDefault（DbSyncCreationOption.Skip）; localProvision.SetCreateProceduresDefault（DbSyncCreationOption.Skip）;

如果您知道之前已经配置了表并且已经创建了存储过程，那么您应该只跳过创建。
