如何通过XML输入参数强制Entity Framework与存储过程一起使用？数据通过Sql连接完美地更新，但我只需要使用实体框架

我尝试过ExecuteFunction和ExecuteStoreQuery都给出了如下所示的不同错误

两个语句都给出错误

return base.ExecuteFunction<int>("pr_UpdateSupplierSubmittedExportdata_1", tblExportDataParameter, batchIDParameter, userNameParameter);
ex = {"The stored procedure or function 'pr_UpdateSupplierSubmittedExportdata_1' does not have a return type. ExecuteFunction only supports stored procedures and functions that have a return type. "}

 return base.ExecuteStoreQuery<int>("Exec pr_UpdateSupplierSubmittedExportdata_1 @tblExportData, @BatchID, @UserName ", tblExportData, batchID, userName);
Must declare the scalar variable "@tblExportData".


var getColumn = (from sp in (objLCSEntities.pr_UpdateSupplierSubmittedExportdata_1(xmlString1, Convert.ToInt32(sExportID), strUserFullName))
                                             select sp).First().ToString();

使用的存储过程：

 CREATE PROCEDURE [UpdateSupplierSubmittedExportdata_1]
    (
          @tblExportData XML,
          @BatchID INT,
          @UserName varchar(200)
          )
    AS

EF是在ADO.NET之上构建的，您始终可以从DbContext访问基础DbConnection来直接使用ADO.NET。

对于EF6，模式为：

        using (var db = new MyDb())
        {
            var con = (SqlConnection) db.Database.Connection;
            con.Open();
            var cmd = con.CreateCommand();
            //...

        }

有关EF核心：

    using (var db = new Db())
    {
        db.Database.OpenConnection();
        var con = (SqlConnection)db.Database.GetDbConnection();
        var cmd = con.CreateCommand();
        //...
    }

在实体模型中使用XM1数据类型执行存储过程
