运行存储过程时的超时时间

Question

我想在EF中运行存储过程。我首先将该过程添加到模型并设置返回值。产生此代码：

public ObjectResult<Report3> SPSelectReport3(global::System.String stringWhereParameter, Nullable<global::System.Int32> pageIndex, Nullable<global::System.Int32> pageSize) 
{ 
    ObjectParameter stringWhereParameterParameter; 
    if (stringWhereParameter != null) 
    { 
     stringWhereParameterParameter = new ObjectParameter("StringWhereParameter", stringWhereParameter); 
    } 
    else 
    { 
     stringWhereParameterParameter = new ObjectParameter("StringWhereParameter", typeof(global::System.String)); 
    } 

    ObjectParameter pageIndexParameter; 
    if (pageIndex.HasValue) 
    { 
     pageIndexParameter = new ObjectParameter("PageIndex", pageIndex); 
    } 
    else 
    { 
     pageIndexParameter = new ObjectParameter("PageIndex", typeof(global::System.Int32)); 
    } 

    ObjectParameter pageSizeParameter; 
    if (pageSize.HasValue) 
    { 
     pageSizeParameter = new ObjectParameter("PageSize", pageSize); 
    } 
    else 
    { 
     pageSizeParameter = new ObjectParameter("PageSize", typeof(global::System.Int32)); 
    } 
    // ((IObjectContextAdapter)this).ObjectContext.CommandTimeout = 999999; 
    return base.ExecuteFunction<Report3>("SPSelectReport3", stringWhereParameterParameter, pageIndexParameter, pageSizeParameter); 
} 
/// <summary> 
/// No Metadata Documentation available. 
/// </summary> 
/// <param name="mergeOption"></param> 
/// <param name="stringWhereParameter">No Metadata Documentation available.</param> 
/// <param name="pageIndex">No Metadata Documentation available.</param> 
/// <param name="pageSize">No Metadata Documentation available.</param> 
public ObjectResult<Report3> SPSelectReport3(global::System.String stringWhereParameter, Nullable<global::System.Int32> pageIndex, Nullable<global::System.Int32> pageSize, MergeOption mergeOption) 
{ 
    ObjectParameter stringWhereParameterParameter; 
    if (stringWhereParameter != null) 
    { 
     stringWhereParameterParameter = new ObjectParameter("StringWhereParameter", stringWhereParameter); 
    } 
    else 
    { 
     stringWhereParameterParameter = new ObjectParameter("StringWhereParameter", typeof(global::System.String)); 
    } 

    ObjectParameter pageIndexParameter; 
    if (pageIndex.HasValue) 
    { 
     pageIndexParameter = new ObjectParameter("PageIndex", pageIndex); 
    } 
    else 
    { 
     pageIndexParameter = new ObjectParameter("PageIndex", typeof(global::System.Int32)); 
    } 

    ObjectParameter pageSizeParameter; 
    if (pageSize.HasValue) 
    { 
     pageSizeParameter = new ObjectParameter("PageSize", pageSize); 
    } 
    else 
    { 
     pageSizeParameter = new ObjectParameter("PageSize", typeof(global::System.Int32)); 
    } 

    // ((IObjectContextAdapter)).ObjectContext.CommandTimeout = 180; 
    return base.ExecuteFunction<Report3>("SPSelectReport3", mergeOption, stringWhereParameterParameter, pageIndexParameter, pageSizeParameter); 
} 

但是当我运行的代码，我得到超时错误。如何在此代码中设置超时时间？

使用的ObjectContext

例如CommandTimeout属性

using (var db = new MyEFEntities()) 
{ 
    string whereClause = "Id = 12345"; 
    db.CommandTimeout = 180; //in seconds, ideally use a value from your config file e.g. Convert.ToInt32(ConfigurationManager.AppSettings["DbCommandTimeout"]); 
    var retval = db.SPSelectReport3(whereClause); 
    //do something here with results 
}
