Incorrect, the OP wants to remove "from" and all after "from", not just "from".

Solution 2

Try this

C#

string test="Remove string from match word.......";
int index1 = test.IndexOf("from");
if (index1 != -1)
{
    string result2 = test.Remove(index1);
}
else
{
  // "from" not found
}

I edited your answer: I removed the second parameter from test.Remove, because if you just write one parameter, then the written parameter is the startIndex parameter, and then all content from startIndex to the end of the string are removed. Also, always check whether the found index isn't -1.

Solution 5

string test="Remove string from match word.......";

// first we get the index of from

int index = test.indexof("from");

test = test.substring(0,index)

Solution 4

Try this,

C#

string test="Remove string from match word.......";

if you want to remove only text "from" then,

C#

test = test.Replace("from","");

If you want to remove "from" and all text after "from" then,

C#

int index = test.IndexOf("from");
test = test.Substring(0,index);
