问题描述
我有两个文本框.在第一个文本框中,假设我写了一个句子我的名字是Mayank",现在我想从第一个文本框中输入一个单词mayank,所以我在第二个文本框中编写了mayank,而不是单击查找"按钮.
我使用了该代码,但命名空间不起作用
Hi ,I have two text boxes.In first text box suppose i write a sentence "My name is Mayank" now i want a word mayank from first text box so i write mayank in second text box than click to Find button.
i used that code but namespace doesn''t work
//namespace DisplayWordJaNein
代码是-
and code is-
string txtfilesentence;
string word;
txtfilesentence = txtshowfile.Text;
word = txtwordmatch.Text;
if (string.Equals(txtfilesentence, word))
{
lblfound.Text = "word matched";
}
else
{
lblnotfound.Text = "word not matched";
}
或如何使用另一个命名空间?
or how to use another namespace ?
推荐答案
将代码更改为此.
Change your code to this .. It will work
string txtfilesentence=string.Empty;
string word=string.Empty;
txtfilesentence = txtshowfile.Text.Trim();
word = txtwordmatch.Text.Trim();
if (txtfilesentence.Contains(word))
{
lblfound.Text = "word matched";
}
else
{
lblnotfound.Text = "word not matched";
}
编辑
Edited
function findit(byRef TheText) as integer
dim i as integer
i=instr(RichTextBox1.text, TheText)
return i
end function
