C# 在嵌套方法中实现嵌套事务的方法

假设我有一个如下所示的类，我如何实现一些东西，使MasterMethod

（MethodA、MethodB和MethodC）中所有被调用的方法继承从
MasterMethod
实例化的
MySqlTransaction
对象

private MySqlConnection OpenConnection() {
    try {
        MySqlConnection DbConn = new MySqlConnection("~connectionstring");
        DbConn.Open();

        return DbConn;
    } catch(Exception Ex) {
        throw Ex;
    }
}

public void MasterMethod() {
    using(MySqlConnection DbConn = OpenConnection()) {
        using(MySqlTransaction DbTrans = DbConn.BeginTransaction()) {
            try {
                MethodA();
                MethodB(Param1);
                MethodC(Param1, Param2);

                DbTrans.Commit();
            } catch(Exception Ex) {
                DbTrans.Rollback();
                throw Ex;
            }
        }
    }
}

public void MethodA() {
    using(MySqlConnection DbConn = OpenConnection()) {
        using(MySqlTransaction DbTrans = DbConn.BeginTransaction()) {
            try {
                // Lots and Lots of things to do

                DbTrans.Commit();
            } catch(Exception Ex) {
                DbTrans.Rollback();
                throw Ex;
            }
        }
    }
}

public void MethodB(int Param1) {
    using(MySqlConnection DbConn = OpenConnection()) {
        using(MySqlTransaction DbTrans = DbConn.BeginTransaction()) {
            try {
                // Lots and Lots of things to do

                DbTrans.Commit();
            } catch(Exception Ex) {
                DbTrans.Rollback();
                throw Ex;
            }
        }
    }
}

public void MethodC(string Param1, string Param2) {
    using(MySqlConnection DbConn = OpenConnection()) {
        using(MySqlTransaction DbTrans = DbConn.BeginTransaction()) {
            try {
                // Lots and Lots of things to do

                DbTrans.Commit();
            } catch(Exception Ex) {
                DbTrans.Rollback();
                throw Ex;
            }
        }
    }
}

在我当前的体系结构中，查询是在特定方法的块到达其末尾后立即提交的，而不是等待MasterMethod的try块最底部的
DbTrans.Commit（）

如何使其
（MySqlTransaction对象）
在提交（或回滚）数据库更改之前，必须等待所有3个嵌套/调用的方法
（MethodA、MethodB、MethodC）

您必须使用2个不同的连接对象来维护状态（根据您的要求）。我已经发布了一个通用的数据库连接代码，你可以用自己的方式使用它

public class ConnectionClass
{
    public string ConnectionString = ConfigurationManager.ConnectionStrings["xyz"].ConnectionString;
    public SqlConnection conTrans = new SqlConnection();
    public SqlTransaction dbTrans;
    public SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["xyz"].ConnectionString);
    public SqlTransaction sqlTrans;



    public bool BeginConTrans()
    {
        try
        {
            conTrans.ConnectionString = ConnectionString;
            conTrans.Open();
            dbTrans = conTrans.BeginTransaction();
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }


    public bool CommitConTrans()
    {
        try
        {
            dbTrans.Commit();
            conTrans.Close();
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }


    public bool RollbackConTrans()
    {
        try
        {
            dbTrans.Rollback();
            conTrans.Close();
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }


    public bool ExecuteNonQueryTrans(string proc, SqlParameter[] par)
    {
        SqlCommand cmd = new SqlCommand();
        try
        {
            if (par != null)
            {

                for (int i = 0; i <= par.Length - 1; i++)
                {
                    cmd.Parameters.Add(par[i]);
                }
            }
            cmd.Connection = conTrans;
            cmd.Transaction = dbTrans;
            cmd.CommandText = proc;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.ExecuteNonQuery();
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }
}

我不知道是我还是你的密码有点。。。你知道的。。。凌乱的我想这是我的错，我忘了我正在使用一个整洁的ORMFramework@TheQuestioner现在检查我的答案。是的，由于一些空格，格式不好：）这可能会派上用场。我会把这个作为参考。问题是我在MySQL服务器下运行，并使用Dapper ORM:）
public void MasterMethod()
    {
        try
        {
            BeginConTrans();
            // your methods A,B,C
            //must use ExecuteNonQueryTrans for your get/put data

        }
        catch (Exception ex)
        {
            //if any method fails handle exception and rollback the transcation
            RollbackConTrans();
        }
        CommitConTrans(); // if success ,commit the transcation

    }
