RDLC报告-如何从小时数（分钟）中计算总时数

Question

I am using RDLC Report. My requirement is, I need to calculate total Hours from values like 9:45 10:02

11:00

Main thing is it including blank values. So How I need to make equation for RDLC Report for getting total hours:minutes.

My current equation is as per below but it gives me #error :

=(TimeSpan.FromTicks(Sum(IIf((Fields!TimeDiff.Value) = " " , System.TimeSpan.Parse("00:00:00"), System.TimeSpan.Parse(Fields!TimeDiff.Value)))).Days * 24 + 
TimeSpan.FromTicks(Sum(IIf((Fields!TimeDiff.Value) = " ", System.TimeSpan.Parse("00:00:00"), System.TimeSpan.Parse(Fields!TimeDiff.Value)))).Hours).ToString +":" + 
TimeSpan.FromTicks(Sum(IIf((Fields!TimeDiff.Value) = " ", System.TimeSpan.Parse("00:00:00"), System.TimeSpan.Parse(Fields!TimeDiff.Value)))).Minutes.ToString("d2")

Thanks for your help.

您可以使用此：

System.TimeSpan.FromTicks(sum(Fields!TimeDiff.Value))
