C# 如何使用时间格式(00:00:00)对行求和并在网格视图的页脚中生成?
作为.Net的初学者,我对我的一个问题感到困惑C# 如何使用时间格式(00:00:00)对行求和并在网格视图的页脚中生成?,c#,asp.net,gridview,C#,Asp.net,Gridview,作为.Net的初学者,我对我的一个问题感到困惑问题是,我在一列中的内容是8:7:15、9:15:12和10:3:4我的问题是,如何添加这三行并在网格视图的页脚中生成27:25:31。我知道如何计算行的总和,但我一直坚持这种格式 任何帮助都会对我更有帮助 提前感谢。您可以尝试以下代码。使用Gridview行数据绑定事件。 在Row-Databound事件中,通过在各个组件中拆分字符串来计算总时间,如下所示 if (e.Row.RowType == DataControlRowType.Foot

我分配三列值返回您的sql查询,并且该值分配为三个字符串,现在我们可以根据您的要求计算该值,请参见下文
string x1 = "8:7:15";//1st column value
string x2 = "9:15:12";//2ndcolumn value
string x3 = "10:3:4";//3rd column value
string[] Cx1 = x1.Split(':');
string[] Cx2 = x2.Split(':');
string[] Cx3 = x3.Split(':');
string Tx1 = ((Convert.ToInt32(Cx1[0]) + Convert.ToInt32(Cx2[0]) + Convert.ToInt32(Cx3[0])) + ":" + (Convert.ToInt32(Cx1[1])
+ Convert.ToInt32(Cx2[1]) + Convert.ToInt32(Cx3[1]))) + ":" + (Convert.ToInt32(Cx1[2]) + Convert.ToInt32(Cx2[2]) + Convert.ToInt32(Cx3[2])).ToString();
最后,您可以将这个Tx1值赋给页脚单元格

string x3 = "10:3:4";//3rd column value

string x5 = "1:1:1";
// , I just assign 5 values,but you can assign more than lot values in this array

现在,您可以在FInalValue变量中获得总的格式化值
最终代码:
string Tvalue1 = "0";
string Tvalue2 = "0";
string Tvalue3 = "0";
for (int i = 0; i < 3; i++)//here 3 is gridview row length
{
string x = "1:1:1";//This your cell value
int n = 3;
string[] xxA = new string[n];
xxA[i] = x;
//Here is the some logic's for the calculation and formating
string[] Cx1 = xxA[i].Split(':');
Tvalue1 = (Convert.ToInt32(Tvalue1) + Convert.ToInt32(Cx1[0])).ToString();
Tvalue2 = (Convert.ToInt32(Tvalue2) + Convert.ToInt32(Cx1[1])).ToString();
Tvalue3 = (Convert.ToInt32(Tvalue3) + Convert.ToInt32(Cx1[2])).ToString();
}
string FInalValue = Tvalue1 + ":" + Tvalue2 + ":" + Tvalue3;
string Tvalue1=“0”;
字符串Tvalue2=“0”;
字符串Tvalue3=“0”;
for(int i=0;i<3;i++)//这里3是gridview行长度
{
string x=“1:1:1”;//这是您的单元格值
int n=3;
字符串[]xxA=新字符串[n];
xxA[i]=x;
//下面是一些用于计算和格式化的逻辑
字符串[]Cx1=xxA[i]。拆分(“:”);
Tvalue1=(Convert.ToInt32(Tvalue1)+Convert.ToInt32(Cx1[0]).ToString();
Tvalue2=(Convert.ToInt32(Tvalue2)+Convert.ToInt32(Cx1[1]).ToString();
Tvalue3=(Convert.ToInt32(Tvalue3)+Convert.ToInt32(Cx1[2]).ToString();
}
