如何检查两个字符串是否相同... [英] how to check the two strings are same...

问题描述

string val1="prince";<br />
string val2="PRINCE";

如何检查两个字符串值是否相等，如果相等，则必须显示一个Confirm box，味精Do u Want to Continue?，否则，如果两个字符串不同，则确认味精为The Two value are different, Do u want to Continue? ，我还需要将这些值保存到数据库.

推荐答案

使用以下代码:

Use the following code:

if(val1.Equals(val2, StringComparison.InvariantCultureIgnoreCase))
{
   // they are the same
}

要显示asp.net对话框，请参见此处: http://www.4guysfromrolla.com/articles/021104-1.aspx [ ^ ]

EDIT :
To show asp.net dialogs see here : http://www.4guysfromrolla.com/articles/021104-1.aspx[^]

protected void Button1_Click(object sender, EventArgs e)
{
   int comp = string.Compare(TextBox1.Text, TextBox2.Text, false);
// true - for case insensitive/ ignore case 
// false - for case sensitive 

        if (comp == 0) // If values are same
        {   
            Response.Write("<script>confirm('The Two Value Are Same. Do you Want to Continue?');</script>");
        }

        else   // If values are different
        {          
            Response.Write("<script>confirm('The Two value are different, Do you  want to Continue?');</script>");
        }
   
}

int result = string.Compare(val1, val2,true);


        if(result == 0)
        {
//Strings are equal

          }
