问题描述
我的应用程序中有两个文本框:
textbox1在formview控件中，而textbox2在formview之外
textbox1具有数据库中的值.
当用户在textbox2中写一些东西(字符串)时，首先想到我要检查一下，
该值存在于textbox1 ...中吗?
如果存在的话，只有我才能继续努力...
应该区分大小写(例如:name和Name不同)
其他
它应该向用户显示消息请输入正确的字符串..."
示例:
Textbox1:一组相关的结构化活动或任务，这些活动或任务为特定客户提供特定服务或产品.
Textbox2:服务
如果我输入Textbox2:服务
它应该显示Message ......
I have two textboxes in my application :
textbox1 is in formview control and textbox2 is out side formview
textbox1 has value from database.
when user write something(string) in textbox2 first think I want to check that,
that value exist in textbox1...?
if it exist than only I can procced furthere...
It should be case sensitive(e.g : name and Name are different)
else
it should display Message to user that "Please enter Correct String..."
Example :
Textbox1 : A collection of related, structured activities or tasks that produce a specific service or product for a particular customer.
Textbox2 : service
if I type in Textbox2 : SErvice
It should display Message......
推荐答案
private void button3_Click(object sender, EventArgs e)
{
string searchWithinThis = textBox4.Text;
string searchForThis = textBox5.Text;
int firstCharacter = searchWithinThis.IndexOf(searchForThis);
if (firstCharacter == -1)
{
MessageBox.Show("please enter correct string");
}
else
{
// do stuff
MessageBox.Show("OK");
}
}
如果您使用按钮进行检查，则将执行此操作.
由于OP的注释而更新了代码；
If you are using a button to check, this will do it.
Updated code due to the OP''s comment;
private void button3_Click(object sender, EventArgs e)
{
string searchWithinThis = textBox1.Text;
int count = searchWithinThis.Split(' ').Length - 1;
bool flag = false;
string[] words = new string[count];
words= searchWithinThis.Split(' ');
for (int i = 0; i < words.Length; i++)
{
if (textBox2.Text == words[i])
{
flag = true;
}
}
if (flag)
{
//do stuff
}
else
{
MessageBox.Show("correct the string");
}
}
private void TextBox2_TextChanged(object sender, EventArgs e)
{
if (this.TextBox2.Text == this.TextBox1.Text)
{
MessageBox.Show("Message here");
}
}
这篇关于textbox2(外部formview控件)将在formview控件内部的textbox1中搜索字符串，如果匹配则比它继续进行，否则显示消息的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
